Introduction Portulaca oleracea L. is a warm-climate, herbaceous succulent annual plant with a cosmopolitan distribution belonging to the Portulacaceae family. It is commonly known as purslane (USA and Australia), rigla (Egypt), pigweed (England), pourpier (France), and Ma-Chi-Xian (China) [1]. It is dis- tributed widely in the tropical and subtropical areas of the world including many parts of the United States and is eaten extensively as a potherb and is added to soups and salads around the Mediterranean and tropical Asian countries [2]. Americans and aborigines of Australia grind the seeds of this plant into flour for use in mush and bread [3]. Portulaca oleracea also provides a source of nutritional benefits owing to its rich omega-3 fatty acids and antioxidant properties [4]. Portulaca oleracea has been used as a folk medicine in many countries, acting as a febrifuge, antiseptic, vermifuge, and so forth [5]. It exhibits a wide range of pharmacological effects, including antibacterial [6], antiulcerogenic [7], anti- inflammatory [8], antioxidant [9], and wound-healing [10] properties. It is listed by the World Health Organization as one of the most used medicinal plants, and it has been given the term “Global Panacea” [11]. e Chinese folklore described it as “vegetable for long life” and it has been used for thousands of years in traditional Chinese Medicine [12, 13]. It is cold in nature and sour in taste and is used to cool the blood, stanch bleeding, clear heat, and resolve toxins. e dried aerial part of this plant is indicated for the treatment of fever, dysentery, diarrhoea, carbuncle, eczema and hematochezia, with a recommended dose of 9–15 g [1416].

Portulaca oleracea has a high potential to be used ashuman and animal food and to be utilized as a pharmaco-logical agent in medicine In this paper phytochemistry andpharmacological activities of this plant are reviewed and itspotential for further investigation exploitation and utiliza-tion are discussed

2 Phytochemistry

Many constituents of Portulaca oleracea have been iso-lated including flavonoids alkaloids fatty acids terpenoidspolysaccharides vitamins sterols proteins and mineralsthese are listed in Table 1 and the chemical structures of themain compounds are presented in Figure 1

One of the most effective constituents present in ChineseHerbal Medicines are flavonoids which are biologically activeand possess a wide range of pharmacological properties suchas antibacterial antivirus anti-inflammation and antioxida-tion properties In the Portulaca oleracea plant the flavonoidslevels vary according to the part of the plant the highest levelsare present in the root followed by stem and the leaf andseven different flavonoids are present in this plant includingkaempferol myricetin luteolin apigenin quercetin genis-tein and genistin [17] However only kaempferol and api-genin have been found in ethanolic extracts of leaves andstems with the levels in the former being higher [11] Portula-canones BndashD three homoisoflavonoids compounds displayselectively cytotoxic activities against three human cancer celllines (SF-268 NCI-H460 and SGC-7901) [18] Flavonoids arealso widely present in foods such as fruits and vegetables [19]

In addition to flavonoids another important chemicalfound in this plant is alkaloids including dopa dopamineandnoradrenalinThe content of dopamine andnoradrenalinis higher in leaves compared to stem and seeds The amountof dopamine and noradrenalin obtained from leaves variesaccording to the solvents used in the extraction processsuggesting that the levels of these compounds are dependenton the solvents used during the extraction process [20]Oleraceins A B C D and E are cyclodopa alkaloids isolatedfrom this plant [21] and several analytes such as (3R)-35-bis(3-methoxy-4-hydroxyphenyl)-23-dihydro-2(1H)-pyridi-none and 15-dimethyl-6-phenyl-12-dihydro-124-triazin-3(2H)-one display cytotoxic activities against human cancercells [22]

Portulaca oleracea is also an excellent source of omega-3 fatty acids which is usually present in oil and fat of fishesbut not normally found in plants Omega-3 fatty acids playan important role in the enhancement of immune function[23] and prevention and treatment of hypertension coronaryartery disease cancer and other inflammatory and autoim-mune disorders [24] It includes 120572-linolenic acid and linoleicacid which are essential for normal growth health pro-motion and disease prevention in humans Polysaccharidesfound in Portulaca oleracea are potential therapeutic agentsfor the treatment of diabetes mellitus owing to their mod-ulation of blood lipids metabolism and decrease of bloodglucose Portulaca oleracea contains monoterpenes such as

portulosides A and B diterpenes such as portulene and 120573-amyrin type triterpenoids [1 25] in addition vitamins havealso been isolated from the leaves of this plant It contains thehighest content of vitamin A which is a natural antioxidantplaying an important role in vision maintaining healthymucus membranes and protecting against lung and oral cav-ity cancers among green leafy vegetablesThis plant also con-tains ascorbic acid 120572-tocopherol and B-complex vitaminsfor example niacin pyridoxine and riboflavin [26] Further-more it is rich in minerals like phosphorus manganese iconcalcium selenium [3] and the amino acids isoleucine prolineleucine lysine phenylalanine methionine cystine valinethreonine and tyrosine [2] Many other constituents havealso been isolated from this plant such as 120573-caroteneglutathione melatonin portulacerebroside A catechol andbergapten

3 Pharmacology

Over the past decades numerous researchers have investi-gated the pharmacological activities of Portulaca oleraceaThis review provides a comprehensive summary of the mainpharmacological properties which are presented below

31 Neuroprotective Activity Administration of Portulacaoleracea can scavenge free radicals and antagonize rotenone-induced neurons apoptosis dopamine depletion and com-plex-I inhibition in striatum of rats suggesting that Portulacaoleraceamay be a potential neuroprotective candidate againstParkinsonrsquos disease [23] The extract of Portulaca oleracea(EP) protects nerve tissuecells from hypoxic damage prob-ably by elevation of glycolysis EPO and hypoxia induciblefactor-1 expression levels [27] The ethanol extract decreasesthe activity of caspase-3 in neuron whilst reducing serumlevels of neuron specific enolase in hypoxia mice and thepathological damages caused by hypoxia In these studiesan increase in the neuron viability and an induction in themRNA and protein expression of endogenous erythropoietinhave also been reported Thus the stabilization of hypoxiainducible factor-1 120572 expression is associated with the neu-roprotective effects of EP against hypoxia injury by elicitingendogenous erythropoietin expression [28] 120573-Cyanin evi-dently inhibits D-galactose-induced neurotoxicity in micewhich at the doses of 50 and 100mgkg upregulates the activi-ties of superoxide dismutases catalase glutathione reductaseand glutathione peroxidase whilst reducing the level of thelipid peroxidation product malondialdehyde in the brain ofD-galactose-treated mice When compared to vitamin C 120573-cyanin play a more pronounced effect on alleviating cogni-tion deficits in mice [29] The total alkaloidal extracts from31 traditional Chinese Herbal Medicines were tested for theiracetylcholinesterase (AChE) inhibitory activities by Ellmanrsquosmethod and modified TLC bioautographic assay As a resultthe alkaloidal extract ofPortulaca oleracea significantly inhib-ited AChE activity at a final concentration of 100 120583gmL withthe IC50 value of 294 120583gmLThe use of AChE inhibitors hasbeen a promising treatment strategy for Alzheimerrsquos disease(AD) therefore Portulaca oleraceamay be an effective agentfor the prophylaxis and treatment of AD [30]

37 Antiulcerogenic Activity Aqueous and ethanolic extractsof Portulaca oleracea at 08 gkg and 14 gkg respectively canreduce the severity of HCl-induced gastric ulcers in a dose-dependent manner this is comparable to the effect observedwith sucralfate 01 gkg In addition the aqueous extract (056and 08 gkg) and the ethanolic extract (08 and 14 gkg)display suppression of lesions induced by absolute ethanolThe oral and intraperitoneal doses of both extracts dose-dependently increase the pH of gastric juice in mice withpylorus ligationThus Portulaca oleracea holds great promiseas an effective therapeutic agent for gastrointestinal diseasesdue to its gastroprotective activity [7]

38 Hepatoprotective Activity Intraperitoneal administra-tion of CCl

4elicits liver injury in rats which notably upreg-

ulates the levels of total bilirubin and serum hepatic markerenzymes including glutamate pyruvate transaminase (GPT)and glutamate oxaloacetate transaminase (GOT) A 70alcohol extract of Portulaca oleracea significantly reverses theincrease in hepatic marker enzymes and total bilirubin levelsconfirming the hepatoprotective activity of this plant [1]

39 Other Activities The ethanol extract from Portulacaoleracea at a concentration range of 100 200 and 400mgkgrespectively displays a dose-dependent effect in prolongingthe survival time of mice in hypoxic models including closednormobaric hypoxia and potassiumcyanide or sodiumnitritetoxicosisThis extract also enhances the activities of phospho-fructokinase pyruvate kinase and lactate dehydrogenase inglycolysis and the level of adenosine triphosphate of mousecortices in hypoxia models [12] The preliminary woundhealing activity of Portulaca oleracea has been appraised inMus musculus JVI-1 and it has been shown that a fresh crudeextract significantly accelerates the wound healing course bythe stimulation of wound contraction and downregulation ofthe surface area of the excisionwound [10] Portulaca oleraceaalso has the ability to accumulate Se even at the shortest timespan of 42 days and hence it can perform the dual functionsof preventing the occurrence of Se deficiency linked diseasessuch as Keshan and Kashin-Beck diseases [47]

4 Conclusion

Portulaca oleracea is of considerable importance to thefood industry and also possesses a wide spectrum of phar-macological properties such as neuroprotective antimi-crobial antidiabetic antioxidant anti-inflammatory antiul-cerogenic and anticancer activities which are associatedwith its diverse chemical constituents including flavonoidsalkaloids polysaccharides fatty acids terpenoids sterolsproteins vitamins and minerals

Although bioactivities of extracts or compounds isolatedfrom Portulaca oleracea are substantiated by using in vitroand in vivo studies including animal models and cell culturestudies the mechanisms of action have not been addressedHence more mechanistic studies are required before Portu-laca oleracea can be considered for further clinical use Thisreview concludes that Portulaca oleracea is an edible and amedicinal plant which is important to the food industry andmay also have a significant role to play in health care providedthat adequate studies are conducted

2 BioMed Research International

Portulaca oleracea has a high potential to be used ashuman and animal food and to be utilized as a pharmaco-logical agent in medicine In this paper phytochemistry andpharmacological activities of this plant are reviewed and itspotential for further investigation exploitation and utiliza-tion are discussed

2 Phytochemistry

Many constituents of Portulaca oleracea have been iso-lated including flavonoids alkaloids fatty acids terpenoidspolysaccharides vitamins sterols proteins and mineralsthese are listed in Table 1 and the chemical structures of themain compounds are presented in Figure 1

One of the most effective constituents present in ChineseHerbal Medicines are flavonoids which are biologically activeand possess a wide range of pharmacological properties suchas antibacterial antivirus anti-inflammation and antioxida-tion properties In the Portulaca oleracea plant the flavonoidslevels vary according to the part of the plant the highest levelsare present in the root followed by stem and the leaf andseven different flavonoids are present in this plant includingkaempferol myricetin luteolin apigenin quercetin genis-tein and genistin [17] However only kaempferol and api-genin have been found in ethanolic extracts of leaves andstems with the levels in the former being higher [11] Portula-canones BndashD three homoisoflavonoids compounds displayselectively cytotoxic activities against three human cancer celllines (SF-268 NCI-H460 and SGC-7901) [18] Flavonoids arealso widely present in foods such as fruits and vegetables [19]

In addition to flavonoids another important chemicalfound in this plant is alkaloids including dopa dopamineandnoradrenalinThe content of dopamine andnoradrenalinis higher in leaves compared to stem and seeds The amountof dopamine and noradrenalin obtained from leaves variesaccording to the solvents used in the extraction processsuggesting that the levels of these compounds are dependenton the solvents used during the extraction process [20]Oleraceins A B C D and E are cyclodopa alkaloids isolatedfrom this plant [21] and several analytes such as (3R)-35-bis(3-methoxy-4-hydroxyphenyl)-23-dihydro-2(1H)-pyridi-none and 15-dimethyl-6-phenyl-12-dihydro-124-triazin-3(2H)-one display cytotoxic activities against human cancercells [22]

Portulaca oleracea is also an excellent source of omega-3 fatty acids which is usually present in oil and fat of fishesbut not normally found in plants Omega-3 fatty acids playan important role in the enhancement of immune function[23] and prevention and treatment of hypertension coronaryartery disease cancer and other inflammatory and autoim-mune disorders [24] It includes 120572-linolenic acid and linoleicacid which are essential for normal growth health pro-motion and disease prevention in humans Polysaccharidesfound in Portulaca oleracea are potential therapeutic agentsfor the treatment of diabetes mellitus owing to their mod-ulation of blood lipids metabolism and decrease of bloodglucose Portulaca oleracea contains monoterpenes such as

portulosides A and B diterpenes such as portulene and 120573-amyrin type triterpenoids [1 25] in addition vitamins havealso been isolated from the leaves of this plant It contains thehighest content of vitamin A which is a natural antioxidantplaying an important role in vision maintaining healthymucus membranes and protecting against lung and oral cav-ity cancers among green leafy vegetablesThis plant also con-tains ascorbic acid 120572-tocopherol and B-complex vitaminsfor example niacin pyridoxine and riboflavin [26] Further-more it is rich in minerals like phosphorus manganese iconcalcium selenium [3] and the amino acids isoleucine prolineleucine lysine phenylalanine methionine cystine valinethreonine and tyrosine [2] Many other constituents havealso been isolated from this plant such as 120573-caroteneglutathione melatonin portulacerebroside A catechol andbergapten

3 Pharmacology

Over the past decades numerous researchers have investi-gated the pharmacological activities of Portulaca oleraceaThis review provides a comprehensive summary of the mainpharmacological properties which are presented below

31 Neuroprotective Activity Administration of Portulacaoleracea can scavenge free radicals and antagonize rotenone-induced neurons apoptosis dopamine depletion and com-plex-I inhibition in striatum of rats suggesting that Portulacaoleraceamay be a potential neuroprotective candidate againstParkinsonrsquos disease [23] The extract of Portulaca oleracea(EP) protects nerve tissuecells from hypoxic damage prob-ably by elevation of glycolysis EPO and hypoxia induciblefactor-1 expression levels [27] The ethanol extract decreasesthe activity of caspase-3 in neuron whilst reducing serumlevels of neuron specific enolase in hypoxia mice and thepathological damages caused by hypoxia In these studiesan increase in the neuron viability and an induction in themRNA and protein expression of endogenous erythropoietinhave also been reported Thus the stabilization of hypoxiainducible factor-1 120572 expression is associated with the neu-roprotective effects of EP against hypoxia injury by elicitingendogenous erythropoietin expression [28] 120573-Cyanin evi-dently inhibits D-galactose-induced neurotoxicity in micewhich at the doses of 50 and 100mgkg upregulates the activi-ties of superoxide dismutases catalase glutathione reductaseand glutathione peroxidase whilst reducing the level of thelipid peroxidation product malondialdehyde in the brain ofD-galactose-treated mice When compared to vitamin C 120573-cyanin play a more pronounced effect on alleviating cogni-tion deficits in mice [29] The total alkaloidal extracts from31 traditional Chinese Herbal Medicines were tested for theiracetylcholinesterase (AChE) inhibitory activities by Ellmanrsquosmethod and modified TLC bioautographic assay As a resultthe alkaloidal extract ofPortulaca oleracea significantly inhib-ited AChE activity at a final concentration of 100 120583gmL withthe IC50 value of 294 120583gmLThe use of AChE inhibitors hasbeen a promising treatment strategy for Alzheimerrsquos disease(AD) therefore Portulaca oleraceamay be an effective agentfor the prophylaxis and treatment of AD [30]

32 Antidiabetic Activity Portulaca oleracea attenuates bodyweight serum free fatty acids and hyperinsulinemia Italso increases insulin sensitivity and ameliorates impairedglucose tolerance and lipid metabolism in rats with type2 diabetes mellitus induced by injection of streptozotocin(25mgkg) and feeding of high calorie forage suggesting thatPortulaca oleracea alleviates insulin resistance [31] Admin-istration of the seeds powder (5 g times 2day) increases highdensity lipoprotein cholesterol (HDLC) and albumin whilelowering the levels of serum total cholesterol triglycerideslow density lipoprotein cholesterol (LDLC) liver gammaglutamyl transaminase (GGT) alanine transaminase (ALT)aspartate transaminase (AST) total and direct bilirubinfasting and postprandial blood glucose insulin body weightand body mass index in type 2 diabetic subjects There wereno differences in these results compared to the data obtainedwith metformin treatment (1500mgday) except for LDLCHDLC and alkaline phosphatase (ALP) levels suggestingthat Portulaca oleracea seeds are valuable and effective as anadjunctive and alternative therapy for the treatment of type 2diabetes mellitus [32]

The aqueous extract of Portulaca oleracea also preventsdiabetic vascular inflammation hyperglycemia and diabeticendothelial dysfunction in type 2 diabetic dbdb micesuggesting its protective role against diabetes and relatedvascular complications [33]The crude polysaccharide extractof this plant also lowers blood glucose and modulates themetabolism of blood lipids and glucose in alloxan-induceddiabeticmice [34] whilst decreasing the levels of total choles-terol triglycerides and fasting blood glucose in type 2diabetic mice [32]

33 Antioxidant Activity The antioxidant property of Por-tulaca oleracea is attributed to its constituents such as gal-lotannins omega-3 fatty acids ascorbic acid 120572-tocopherolskaempferol quercetin and apigenin [8 16 17]The single cellgel electrophoresis assay (comet assay) which is an simplerapid and inexpensive method for measuring DNA strandbreaks confirmed that the aqueous extract significantlyalleviated hydrogen peroxide-induced oxidative DNA lesionsin human lymphocytes whereas the ethanolic extract had noeffects which may be associated with the antioxidant con-stituents contained in the aqueous extract [35] The aqueousextract decreases high fat diet-elicited oxidative damage bymodulating blood and liver antioxidant enzyme activitieselevating leptin120573-actin and liver PPARa120573-actin and inhibit-ing the protein expression of p-PERK and the FAS mRNAexpression of liver and spleen in mice [9] In another studythe aqueous extract at a concentration range of 100 150 200and 400 120583gmL and the ethanolic extract at a range of 1200and 1800 120583gmL respectively exerted cytoprotective effects

on 221015840-azobis hydrochloride-induced hemolytic damages ofRBCs in a concentration-dependent manner [36]

34 Anticancer Activity Polysaccharides from Portulacaoleracea display several biological activities such as anti-cancer antioxidation anti-inflammation and immunityenhancing properties [37ndash40] Polysaccharides evidentlyscavenge the accumulation of free radicals and modulateimmunity functions of rats with ovarian cancer [41] Sulfatedderivatives of POP a water-soluble polysaccharide isolatedfrom Portulaca oleracea have a suppressive effect on thegrowth of HeLa and HepG2 cells in vitro suggesting that thesulfation of POP increases the cytotoxicity in tumor cells [42]In addition to polysaccharides other bioactive compoundssuch as cerebrosides homoisoflavonoids and alkaloids alsoshow in vitro cytotoxic activities against human cancer celllines Portulacerebroside A stimulates human liver cancerHCCLM3 cell apoptosis via the activation of the p38 MAPK-and JNK-triggered mitochondrial death pathway [43] and221015840-dihydroxy-4101584061015840-dimethoxychalcone is more activeagainst cell line SGC-7901 with an IC

Figure 1 Chemical structures of main compounds present in Portulaca oleracea

inhibition zones of 13 14 and 15mm respectively as well asantifungal activity against Candida albicans with inhibitionzone of 12mm [1]

36 Anti-Inflammatory Activity Pretreatment with the aque-ous extract of Portulaca oleracea inhibits tumor necrosisfactor- (TNF-) 120572-induced production of intracellular reac-tive oxygen species (ROS) and overexpression of intercel-lular adhesion molecule- (ICAM-) 1 vascular cell adhesionmolecule (VCAM)-1 and E-selectin in human umbilical veinendothelial cells (HUVECs) in a dose-dependent mannerThis extract also suppresses the translocation of nuclearfactor 120581B (NF-120581B) p65 to the nucleus TNF-120572-inducedNF-120581Bbinding and the degradation of inhibitor molecule (I120581B)120572Furthermore an inhibition in the adhesion of HL-60 cellsto TNF-120572-induced HUVECs and TNF-120572-induced mRNAexpression of interleukin- (IL-) 8 andmonocyte chemoattrac-tant protein- (MCP-) 1 is also observed The aqueous extractof Portulaca oleracea may also play an important role in thesuppression of the vascular inflammatory process related tothe development of atherosclerosis [46]

37 Antiulcerogenic Activity Aqueous and ethanolic extractsof Portulaca oleracea at 08 gkg and 14 gkg respectively canreduce the severity of HCl-induced gastric ulcers in a dose-dependent manner this is comparable to the effect observedwith sucralfate 01 gkg In addition the aqueous extract (056and 08 gkg) and the ethanolic extract (08 and 14 gkg)display suppression of lesions induced by absolute ethanolThe oral and intraperitoneal doses of both extracts dose-dependently increase the pH of gastric juice in mice withpylorus ligationThus Portulaca oleracea holds great promiseas an effective therapeutic agent for gastrointestinal diseasesdue to its gastroprotective activity [7]

38 Hepatoprotective Activity Intraperitoneal administra-tion of CCl

4elicits liver injury in rats which notably upreg-

ulates the levels of total bilirubin and serum hepatic markerenzymes including glutamate pyruvate transaminase (GPT)and glutamate oxaloacetate transaminase (GOT) A 70alcohol extract of Portulaca oleracea significantly reverses theincrease in hepatic marker enzymes and total bilirubin levelsconfirming the hepatoprotective activity of this plant [1]

39 Other Activities The ethanol extract from Portulacaoleracea at a concentration range of 100 200 and 400mgkgrespectively displays a dose-dependent effect in prolongingthe survival time of mice in hypoxic models including closednormobaric hypoxia and potassiumcyanide or sodiumnitritetoxicosisThis extract also enhances the activities of phospho-fructokinase pyruvate kinase and lactate dehydrogenase inglycolysis and the level of adenosine triphosphate of mousecortices in hypoxia models [12] The preliminary woundhealing activity of Portulaca oleracea has been appraised inMus musculus JVI-1 and it has been shown that a fresh crudeextract significantly accelerates the wound healing course bythe stimulation of wound contraction and downregulation ofthe surface area of the excisionwound [10] Portulaca oleraceaalso has the ability to accumulate Se even at the shortest timespan of 42 days and hence it can perform the dual functionsof preventing the occurrence of Se deficiency linked diseasessuch as Keshan and Kashin-Beck diseases [47]

4 Conclusion

Portulaca oleracea is of considerable importance to thefood industry and also possesses a wide spectrum of phar-macological properties such as neuroprotective antimi-crobial antidiabetic antioxidant anti-inflammatory antiul-cerogenic and anticancer activities which are associatedwith its diverse chemical constituents including flavonoidsalkaloids polysaccharides fatty acids terpenoids sterolsproteins vitamins and minerals

Although bioactivities of extracts or compounds isolatedfrom Portulaca oleracea are substantiated by using in vitroand in vivo studies including animal models and cell culturestudies the mechanisms of action have not been addressedHence more mechanistic studies are required before Portu-laca oleracea can be considered for further clinical use Thisreview concludes that Portulaca oleracea is an edible and amedicinal plant which is important to the food industry andmay also have a significant role to play in health care providedthat adequate studies are conducted

32 Antidiabetic Activity Portulaca oleracea attenuates bodyweight serum free fatty acids and hyperinsulinemia Italso increases insulin sensitivity and ameliorates impairedglucose tolerance and lipid metabolism in rats with type2 diabetes mellitus induced by injection of streptozotocin(25mgkg) and feeding of high calorie forage suggesting thatPortulaca oleracea alleviates insulin resistance [31] Admin-istration of the seeds powder (5 g times 2day) increases highdensity lipoprotein cholesterol (HDLC) and albumin whilelowering the levels of serum total cholesterol triglycerideslow density lipoprotein cholesterol (LDLC) liver gammaglutamyl transaminase (GGT) alanine transaminase (ALT)aspartate transaminase (AST) total and direct bilirubinfasting and postprandial blood glucose insulin body weightand body mass index in type 2 diabetic subjects There wereno differences in these results compared to the data obtainedwith metformin treatment (1500mgday) except for LDLCHDLC and alkaline phosphatase (ALP) levels suggestingthat Portulaca oleracea seeds are valuable and effective as anadjunctive and alternative therapy for the treatment of type 2diabetes mellitus [32]

The aqueous extract of Portulaca oleracea also preventsdiabetic vascular inflammation hyperglycemia and diabeticendothelial dysfunction in type 2 diabetic dbdb micesuggesting its protective role against diabetes and relatedvascular complications [33]The crude polysaccharide extractof this plant also lowers blood glucose and modulates themetabolism of blood lipids and glucose in alloxan-induceddiabeticmice [34] whilst decreasing the levels of total choles-terol triglycerides and fasting blood glucose in type 2diabetic mice [32]

33 Antioxidant Activity The antioxidant property of Por-tulaca oleracea is attributed to its constituents such as gal-lotannins omega-3 fatty acids ascorbic acid 120572-tocopherolskaempferol quercetin and apigenin [8 16 17]The single cellgel electrophoresis assay (comet assay) which is an simplerapid and inexpensive method for measuring DNA strandbreaks confirmed that the aqueous extract significantlyalleviated hydrogen peroxide-induced oxidative DNA lesionsin human lymphocytes whereas the ethanolic extract had noeffects which may be associated with the antioxidant con-stituents contained in the aqueous extract [35] The aqueousextract decreases high fat diet-elicited oxidative damage bymodulating blood and liver antioxidant enzyme activitieselevating leptin120573-actin and liver PPARa120573-actin and inhibit-ing the protein expression of p-PERK and the FAS mRNAexpression of liver and spleen in mice [9] In another studythe aqueous extract at a concentration range of 100 150 200and 400 120583gmL and the ethanolic extract at a range of 1200and 1800 120583gmL respectively exerted cytoprotective effects

on 221015840-azobis hydrochloride-induced hemolytic damages ofRBCs in a concentration-dependent manner [36]

34 Anticancer Activity Polysaccharides from Portulacaoleracea display several biological activities such as anti-cancer antioxidation anti-inflammation and immunityenhancing properties [37ndash40] Polysaccharides evidentlyscavenge the accumulation of free radicals and modulateimmunity functions of rats with ovarian cancer [41] Sulfatedderivatives of POP a water-soluble polysaccharide isolatedfrom Portulaca oleracea have a suppressive effect on thegrowth of HeLa and HepG2 cells in vitro suggesting that thesulfation of POP increases the cytotoxicity in tumor cells [42]In addition to polysaccharides other bioactive compoundssuch as cerebrosides homoisoflavonoids and alkaloids alsoshow in vitro cytotoxic activities against human cancer celllines Portulacerebroside A stimulates human liver cancerHCCLM3 cell apoptosis via the activation of the p38 MAPK-and JNK-triggered mitochondrial death pathway [43] and221015840-dihydroxy-4101584061015840-dimethoxychalcone is more activeagainst cell line SGC-7901 with an IC

inhibition zones of 13 14 and 15mm respectively as well asantifungal activity against Candida albicans with inhibitionzone of 12mm [1]

36 Anti-Inflammatory Activity Pretreatment with the aque-ous extract of Portulaca oleracea inhibits tumor necrosisfactor- (TNF-) 120572-induced production of intracellular reac-tive oxygen species (ROS) and overexpression of intercel-lular adhesion molecule- (ICAM-) 1 vascular cell adhesionmolecule (VCAM)-1 and E-selectin in human umbilical veinendothelial cells (HUVECs) in a dose-dependent mannerThis extract also suppresses the translocation of nuclearfactor 120581B (NF-120581B) p65 to the nucleus TNF-120572-inducedNF-120581Bbinding and the degradation of inhibitor molecule (I120581B)120572Furthermore an inhibition in the adhesion of HL-60 cellsto TNF-120572-induced HUVECs and TNF-120572-induced mRNAexpression of interleukin- (IL-) 8 andmonocyte chemoattrac-tant protein- (MCP-) 1 is also observed The aqueous extractof Portulaca oleracea may also play an important role in thesuppression of the vascular inflammatory process related tothe development of atherosclerosis [46]

37 Antiulcerogenic Activity Aqueous and ethanolic extractsof Portulaca oleracea at 08 gkg and 14 gkg respectively canreduce the severity of HCl-induced gastric ulcers in a dose-dependent manner this is comparable to the effect observedwith sucralfate 01 gkg In addition the aqueous extract (056and 08 gkg) and the ethanolic extract (08 and 14 gkg)display suppression of lesions induced by absolute ethanolThe oral and intraperitoneal doses of both extracts dose-dependently increase the pH of gastric juice in mice withpylorus ligationThus Portulaca oleracea holds great promiseas an effective therapeutic agent for gastrointestinal diseasesdue to its gastroprotective activity [7]

38 Hepatoprotective Activity Intraperitoneal administra-tion of CCl

4elicits liver injury in rats which notably upreg-

ulates the levels of total bilirubin and serum hepatic markerenzymes including glutamate pyruvate transaminase (GPT)and glutamate oxaloacetate transaminase (GOT) A 70alcohol extract of Portulaca oleracea significantly reverses theincrease in hepatic marker enzymes and total bilirubin levelsconfirming the hepatoprotective activity of this plant [1]

39 Other Activities The ethanol extract from Portulacaoleracea at a concentration range of 100 200 and 400mgkgrespectively displays a dose-dependent effect in prolongingthe survival time of mice in hypoxic models including closednormobaric hypoxia and potassiumcyanide or sodiumnitritetoxicosisThis extract also enhances the activities of phospho-fructokinase pyruvate kinase and lactate dehydrogenase inglycolysis and the level of adenosine triphosphate of mousecortices in hypoxia models [12] The preliminary woundhealing activity of Portulaca oleracea has been appraised inMus musculus JVI-1 and it has been shown that a fresh crudeextract significantly accelerates the wound healing course bythe stimulation of wound contraction and downregulation ofthe surface area of the excisionwound [10] Portulaca oleraceaalso has the ability to accumulate Se even at the shortest timespan of 42 days and hence it can perform the dual functionsof preventing the occurrence of Se deficiency linked diseasessuch as Keshan and Kashin-Beck diseases [47]

4 Conclusion

Portulaca oleracea is of considerable importance to thefood industry and also possesses a wide spectrum of phar-macological properties such as neuroprotective antimi-crobial antidiabetic antioxidant anti-inflammatory antiul-cerogenic and anticancer activities which are associatedwith its diverse chemical constituents including flavonoidsalkaloids polysaccharides fatty acids terpenoids sterolsproteins vitamins and minerals

Although bioactivities of extracts or compounds isolatedfrom Portulaca oleracea are substantiated by using in vitroand in vivo studies including animal models and cell culturestudies the mechanisms of action have not been addressedHence more mechanistic studies are required before Portu-laca oleracea can be considered for further clinical use Thisreview concludes that Portulaca oleracea is an edible and amedicinal plant which is important to the food industry andmay also have a significant role to play in health care providedthat adequate studies are conducted

32 Antidiabetic Activity Portulaca oleracea attenuates bodyweight serum free fatty acids and hyperinsulinemia Italso increases insulin sensitivity and ameliorates impairedglucose tolerance and lipid metabolism in rats with type2 diabetes mellitus induced by injection of streptozotocin(25mgkg) and feeding of high calorie forage suggesting thatPortulaca oleracea alleviates insulin resistance [31] Admin-istration of the seeds powder (5 g times 2day) increases highdensity lipoprotein cholesterol (HDLC) and albumin whilelowering the levels of serum total cholesterol triglycerideslow density lipoprotein cholesterol (LDLC) liver gammaglutamyl transaminase (GGT) alanine transaminase (ALT)aspartate transaminase (AST) total and direct bilirubinfasting and postprandial blood glucose insulin body weightand body mass index in type 2 diabetic subjects There wereno differences in these results compared to the data obtainedwith metformin treatment (1500mgday) except for LDLCHDLC and alkaline phosphatase (ALP) levels suggestingthat Portulaca oleracea seeds are valuable and effective as anadjunctive and alternative therapy for the treatment of type 2diabetes mellitus [32]

The aqueous extract of Portulaca oleracea also preventsdiabetic vascular inflammation hyperglycemia and diabeticendothelial dysfunction in type 2 diabetic dbdb micesuggesting its protective role against diabetes and relatedvascular complications [33]The crude polysaccharide extractof this plant also lowers blood glucose and modulates themetabolism of blood lipids and glucose in alloxan-induceddiabeticmice [34] whilst decreasing the levels of total choles-terol triglycerides and fasting blood glucose in type 2diabetic mice [32]

33 Antioxidant Activity The antioxidant property of Por-tulaca oleracea is attributed to its constituents such as gal-lotannins omega-3 fatty acids ascorbic acid 120572-tocopherolskaempferol quercetin and apigenin [8 16 17]The single cellgel electrophoresis assay (comet assay) which is an simplerapid and inexpensive method for measuring DNA strandbreaks confirmed that the aqueous extract significantlyalleviated hydrogen peroxide-induced oxidative DNA lesionsin human lymphocytes whereas the ethanolic extract had noeffects which may be associated with the antioxidant con-stituents contained in the aqueous extract [35] The aqueousextract decreases high fat diet-elicited oxidative damage bymodulating blood and liver antioxidant enzyme activitieselevating leptin120573-actin and liver PPARa120573-actin and inhibit-ing the protein expression of p-PERK and the FAS mRNAexpression of liver and spleen in mice [9] In another studythe aqueous extract at a concentration range of 100 150 200and 400 120583gmL and the ethanolic extract at a range of 1200and 1800 120583gmL respectively exerted cytoprotective effects

on 221015840-azobis hydrochloride-induced hemolytic damages ofRBCs in a concentration-dependent manner [36]

34 Anticancer Activity Polysaccharides from Portulacaoleracea display several biological activities such as anti-cancer antioxidation anti-inflammation and immunityenhancing properties [37ndash40] Polysaccharides evidentlyscavenge the accumulation of free radicals and modulateimmunity functions of rats with ovarian cancer [41] Sulfatedderivatives of POP a water-soluble polysaccharide isolatedfrom Portulaca oleracea have a suppressive effect on thegrowth of HeLa and HepG2 cells in vitro suggesting that thesulfation of POP increases the cytotoxicity in tumor cells [42]In addition to polysaccharides other bioactive compoundssuch as cerebrosides homoisoflavonoids and alkaloids alsoshow in vitro cytotoxic activities against human cancer celllines Portulacerebroside A stimulates human liver cancerHCCLM3 cell apoptosis via the activation of the p38 MAPK-and JNK-triggered mitochondrial death pathway [43] and221015840-dihydroxy-4101584061015840-dimethoxychalcone is more activeagainst cell line SGC-7901 with an IC

Figure 1 Chemical structures of main compounds present in Portulaca oleracea

inhibition zones of 13 14 and 15mm respectively as well asantifungal activity against Candida albicans with inhibitionzone of 12mm [1]

36 Anti-Inflammatory Activity Pretreatment with the aque-ous extract of Portulaca oleracea inhibits tumor necrosisfactor- (TNF-) 120572-induced production of intracellular reac-tive oxygen species (ROS) and overexpression of intercel-lular adhesion molecule- (ICAM-) 1 vascular cell adhesionmolecule (VCAM)-1 and E-selectin in human umbilical veinendothelial cells (HUVECs) in a dose-dependent mannerThis extract also suppresses the translocation of nuclearfactor 120581B (NF-120581B) p65 to the nucleus TNF-120572-inducedNF-120581Bbinding and the degradation of inhibitor molecule (I120581B)120572Furthermore an inhibition in the adhesion of HL-60 cellsto TNF-120572-induced HUVECs and TNF-120572-induced mRNAexpression of interleukin- (IL-) 8 andmonocyte chemoattrac-tant protein- (MCP-) 1 is also observed The aqueous extractof Portulaca oleracea may also play an important role in thesuppression of the vascular inflammatory process related tothe development of atherosclerosis [46]

37 Antiulcerogenic Activity Aqueous and ethanolic extractsof Portulaca oleracea at 08 gkg and 14 gkg respectively canreduce the severity of HCl-induced gastric ulcers in a dose-dependent manner this is comparable to the effect observedwith sucralfate 01 gkg In addition the aqueous extract (056and 08 gkg) and the ethanolic extract (08 and 14 gkg)display suppression of lesions induced by absolute ethanolThe oral and intraperitoneal doses of both extracts dose-dependently increase the pH of gastric juice in mice withpylorus ligationThus Portulaca oleracea holds great promiseas an effective therapeutic agent for gastrointestinal diseasesdue to its gastroprotective activity [7]

38 Hepatoprotective Activity Intraperitoneal administra-tion of CCl

4elicits liver injury in rats which notably upreg-

ulates the levels of total bilirubin and serum hepatic markerenzymes including glutamate pyruvate transaminase (GPT)and glutamate oxaloacetate transaminase (GOT) A 70alcohol extract of Portulaca oleracea significantly reverses theincrease in hepatic marker enzymes and total bilirubin levelsconfirming the hepatoprotective activity of this plant [1]

39 Other Activities The ethanol extract from Portulacaoleracea at a concentration range of 100 200 and 400mgkgrespectively displays a dose-dependent effect in prolongingthe survival time of mice in hypoxic models including closednormobaric hypoxia and potassiumcyanide or sodiumnitritetoxicosisThis extract also enhances the activities of phospho-fructokinase pyruvate kinase and lactate dehydrogenase inglycolysis and the level of adenosine triphosphate of mousecortices in hypoxia models [12] The preliminary woundhealing activity of Portulaca oleracea has been appraised inMus musculus JVI-1 and it has been shown that a fresh crudeextract significantly accelerates the wound healing course bythe stimulation of wound contraction and downregulation ofthe surface area of the excisionwound [10] Portulaca oleraceaalso has the ability to accumulate Se even at the shortest timespan of 42 days and hence it can perform the dual functionsof preventing the occurrence of Se deficiency linked diseasessuch as Keshan and Kashin-Beck diseases [47]

4 Conclusion

Portulaca oleracea is of considerable importance to thefood industry and also possesses a wide spectrum of phar-macological properties such as neuroprotective antimi-crobial antidiabetic antioxidant anti-inflammatory antiul-cerogenic and anticancer activities which are associatedwith its diverse chemical constituents including flavonoidsalkaloids polysaccharides fatty acids terpenoids sterolsproteins vitamins and minerals

Although bioactivities of extracts or compounds isolatedfrom Portulaca oleracea are substantiated by using in vitroand in vivo studies including animal models and cell culturestudies the mechanisms of action have not been addressedHence more mechanistic studies are required before Portu-laca oleracea can be considered for further clinical use Thisreview concludes that Portulaca oleracea is an edible and amedicinal plant which is important to the food industry andmay also have a significant role to play in health care providedthat adequate studies are conducted

32 Antidiabetic Activity Portulaca oleracea attenuates bodyweight serum free fatty acids and hyperinsulinemia Italso increases insulin sensitivity and ameliorates impairedglucose tolerance and lipid metabolism in rats with type2 diabetes mellitus induced by injection of streptozotocin(25mgkg) and feeding of high calorie forage suggesting thatPortulaca oleracea alleviates insulin resistance [31] Admin-istration of the seeds powder (5 g times 2day) increases highdensity lipoprotein cholesterol (HDLC) and albumin whilelowering the levels of serum total cholesterol triglycerideslow density lipoprotein cholesterol (LDLC) liver gammaglutamyl transaminase (GGT) alanine transaminase (ALT)aspartate transaminase (AST) total and direct bilirubinfasting and postprandial blood glucose insulin body weightand body mass index in type 2 diabetic subjects There wereno differences in these results compared to the data obtainedwith metformin treatment (1500mgday) except for LDLCHDLC and alkaline phosphatase (ALP) levels suggestingthat Portulaca oleracea seeds are valuable and effective as anadjunctive and alternative therapy for the treatment of type 2diabetes mellitus [32]

The aqueous extract of Portulaca oleracea also preventsdiabetic vascular inflammation hyperglycemia and diabeticendothelial dysfunction in type 2 diabetic dbdb micesuggesting its protective role against diabetes and relatedvascular complications [33]The crude polysaccharide extractof this plant also lowers blood glucose and modulates themetabolism of blood lipids and glucose in alloxan-induceddiabeticmice [34] whilst decreasing the levels of total choles-terol triglycerides and fasting blood glucose in type 2diabetic mice [32]

33 Antioxidant Activity The antioxidant property of Por-tulaca oleracea is attributed to its constituents such as gal-lotannins omega-3 fatty acids ascorbic acid 120572-tocopherolskaempferol quercetin and apigenin [8 16 17]The single cellgel electrophoresis assay (comet assay) which is an simplerapid and inexpensive method for measuring DNA strandbreaks confirmed that the aqueous extract significantlyalleviated hydrogen peroxide-induced oxidative DNA lesionsin human lymphocytes whereas the ethanolic extract had noeffects which may be associated with the antioxidant con-stituents contained in the aqueous extract [35] The aqueousextract decreases high fat diet-elicited oxidative damage bymodulating blood and liver antioxidant enzyme activitieselevating leptin120573-actin and liver PPARa120573-actin and inhibit-ing the protein expression of p-PERK and the FAS mRNAexpression of liver and spleen in mice [9] In another studythe aqueous extract at a concentration range of 100 150 200and 400 120583gmL and the ethanolic extract at a range of 1200and 1800 120583gmL respectively exerted cytoprotective effects

on 221015840-azobis hydrochloride-induced hemolytic damages ofRBCs in a concentration-dependent manner [36]

34 Anticancer Activity Polysaccharides from Portulacaoleracea display several biological activities such as anti-cancer antioxidation anti-inflammation and immunityenhancing properties [37ndash40] Polysaccharides evidentlyscavenge the accumulation of free radicals and modulateimmunity functions of rats with ovarian cancer [41] Sulfatedderivatives of POP a water-soluble polysaccharide isolatedfrom Portulaca oleracea have a suppressive effect on thegrowth of HeLa and HepG2 cells in vitro suggesting that thesulfation of POP increases the cytotoxicity in tumor cells [42]In addition to polysaccharides other bioactive compoundssuch as cerebrosides homoisoflavonoids and alkaloids alsoshow in vitro cytotoxic activities against human cancer celllines Portulacerebroside A stimulates human liver cancerHCCLM3 cell apoptosis via the activation of the p38 MAPK-and JNK-triggered mitochondrial death pathway [43] and221015840-dihydroxy-4101584061015840-dimethoxychalcone is more activeagainst cell line SGC-7901 with an IC

than mitomycin C which has an IC50

value of 130 ugmLPortulacanones B is active against SGC-7901 cell lines withan IC

50value of 162 ugmL which is very close to the

value obtained with mitomycin C 221015840-Dihydroxy-4101584061015840-dimethoxychalcone is moderately active against K-562 cellswith an IC

50value of 246 ugmL and portulacanones BndashD

show selective cytotoxic activity against SF-268 andorNCI-H460 cells with IC

50values of 143ndash201 ugmL [18] N-

trans-Feruloyltyramine (71015840R)-N-feruloylnormetanephrine15-dimethyl-6-phenyl-12-dihydro-124-triazin-3(2H)-oneand (3R)-35-bis(3-methoxy-4-hydroxyphenyl)-23-dihydro-2(1H)-pyridinone have weak bioactivities against K562with IC

50values of 22277 6694 9009 and 4152 umolL

respectively and moderate bioactivities against A549 withIC50

values of 2880 2176 2454 and 3720 umolL respec-tively [22] These studies demonstrate that Portulaca oleraceahas a potential application in the treatment of cancer

35 Antimicrobial Portulaca oleracea possesses antibacterialantifungal and antiviral activities as revealed by its antifungaleffect against dermatophytes of the genera Trichophyton [44]A pectic polysaccharide isolated from the aerial part of thisplant displays antiherpes property against simplex virus type2 which is due to the inhibition of virus penetration and notvirus adsorption [45] A 70 methyl alcohol extract of Por-tulaca oleracea shows antibacterial activity against the Gram-negative stains Escherichia coli Pseudomonas aeruginosaand Neisseria gonorrhea with inhibition zones of 14 15 and15mm respectively and the Gram-positive strains Staphylo-coccus aureus Bacillus subtilis and Streptococcus faecaliswith

Figure 1 Chemical structures of main compounds present in Portulaca oleracea

inhibition zones of 13 14 and 15mm respectively as well asantifungal activity against Candida albicans with inhibitionzone of 12mm [1]

36 Anti-Inflammatory Activity Pretreatment with the aque-ous extract of Portulaca oleracea inhibits tumor necrosisfactor- (TNF-) 120572-induced production of intracellular reac-tive oxygen species (ROS) and overexpression of intercel-lular adhesion molecule- (ICAM-) 1 vascular cell adhesionmolecule (VCAM)-1 and E-selectin in human umbilical veinendothelial cells (HUVECs) in a dose-dependent mannerThis extract also suppresses the translocation of nuclearfactor 120581B (NF-120581B) p65 to the nucleus TNF-120572-inducedNF-120581Bbinding and the degradation of inhibitor molecule (I120581B)120572Furthermore an inhibition in the adhesion of HL-60 cellsto TNF-120572-induced HUVECs and TNF-120572-induced mRNAexpression of interleukin- (IL-) 8 andmonocyte chemoattrac-tant protein- (MCP-) 1 is also observed The aqueous extractof Portulaca oleracea may also play an important role in thesuppression of the vascular inflammatory process related tothe development of atherosclerosis [46]

37 Antiulcerogenic Activity Aqueous and ethanolic extractsof Portulaca oleracea at 08 gkg and 14 gkg respectively canreduce the severity of HCl-induced gastric ulcers in a dose-dependent manner this is comparable to the effect observedwith sucralfate 01 gkg In addition the aqueous extract (056and 08 gkg) and the ethanolic extract (08 and 14 gkg)display suppression of lesions induced by absolute ethanolThe oral and intraperitoneal doses of both extracts dose-dependently increase the pH of gastric juice in mice withpylorus ligationThus Portulaca oleracea holds great promiseas an effective therapeutic agent for gastrointestinal diseasesdue to its gastroprotective activity [7]

38 Hepatoprotective Activity Intraperitoneal administra-tion of CCl

4elicits liver injury in rats which notably upreg-

ulates the levels of total bilirubin and serum hepatic markerenzymes including glutamate pyruvate transaminase (GPT)and glutamate oxaloacetate transaminase (GOT) A 70alcohol extract of Portulaca oleracea significantly reverses theincrease in hepatic marker enzymes and total bilirubin levelsconfirming the hepatoprotective activity of this plant [1]

39 Other Activities The ethanol extract from Portulacaoleracea at a concentration range of 100 200 and 400mgkgrespectively displays a dose-dependent effect in prolongingthe survival time of mice in hypoxic models including closednormobaric hypoxia and potassiumcyanide or sodiumnitritetoxicosisThis extract also enhances the activities of phospho-fructokinase pyruvate kinase and lactate dehydrogenase inglycolysis and the level of adenosine triphosphate of mousecortices in hypoxia models [12] The preliminary woundhealing activity of Portulaca oleracea has been appraised inMus musculus JVI-1 and it has been shown that a fresh crudeextract significantly accelerates the wound healing course bythe stimulation of wound contraction and downregulation ofthe surface area of the excisionwound [10] Portulaca oleraceaalso has the ability to accumulate Se even at the shortest timespan of 42 days and hence it can perform the dual functionsof preventing the occurrence of Se deficiency linked diseasessuch as Keshan and Kashin-Beck diseases [47]

4 Conclusion

Portulaca oleracea is of considerable importance to thefood industry and also possesses a wide spectrum of phar-macological properties such as neuroprotective antimi-crobial antidiabetic antioxidant anti-inflammatory antiul-cerogenic and anticancer activities which are associatedwith its diverse chemical constituents including flavonoidsalkaloids polysaccharides fatty acids terpenoids sterolsproteins vitamins and minerals

Although bioactivities of extracts or compounds isolatedfrom Portulaca oleracea are substantiated by using in vitroand in vivo studies including animal models and cell culturestudies the mechanisms of action have not been addressedHence more mechanistic studies are required before Portu-laca oleracea can be considered for further clinical use Thisreview concludes that Portulaca oleracea is an edible and amedicinal plant which is important to the food industry andmay also have a significant role to play in health care providedthat adequate studies are conducted

Figure 1 Chemical structures of main compounds present in Portulaca oleracea

inhibition zones of 13 14 and 15mm respectively as well asantifungal activity against Candida albicans with inhibitionzone of 12mm [1]

36 Anti-Inflammatory Activity Pretreatment with the aque-ous extract of Portulaca oleracea inhibits tumor necrosisfactor- (TNF-) 120572-induced production of intracellular reac-tive oxygen species (ROS) and overexpression of intercel-lular adhesion molecule- (ICAM-) 1 vascular cell adhesionmolecule (VCAM)-1 and E-selectin in human umbilical veinendothelial cells (HUVECs) in a dose-dependent mannerThis extract also suppresses the translocation of nuclearfactor 120581B (NF-120581B) p65 to the nucleus TNF-120572-inducedNF-120581Bbinding and the degradation of inhibitor molecule (I120581B)120572Furthermore an inhibition in the adhesion of HL-60 cellsto TNF-120572-induced HUVECs and TNF-120572-induced mRNAexpression of interleukin- (IL-) 8 andmonocyte chemoattrac-tant protein- (MCP-) 1 is also observed The aqueous extractof Portulaca oleracea may also play an important role in thesuppression of the vascular inflammatory process related tothe development of atherosclerosis [46]

37 Antiulcerogenic Activity Aqueous and ethanolic extractsof Portulaca oleracea at 08 gkg and 14 gkg respectively canreduce the severity of HCl-induced gastric ulcers in a dose-dependent manner this is comparable to the effect observedwith sucralfate 01 gkg In addition the aqueous extract (056and 08 gkg) and the ethanolic extract (08 and 14 gkg)display suppression of lesions induced by absolute ethanolThe oral and intraperitoneal doses of both extracts dose-dependently increase the pH of gastric juice in mice withpylorus ligationThus Portulaca oleracea holds great promiseas an effective therapeutic agent for gastrointestinal diseasesdue to its gastroprotective activity [7]

38 Hepatoprotective Activity Intraperitoneal administra-tion of CCl

4elicits liver injury in rats which notably upreg-

ulates the levels of total bilirubin and serum hepatic markerenzymes including glutamate pyruvate transaminase (GPT)and glutamate oxaloacetate transaminase (GOT) A 70alcohol extract of Portulaca oleracea significantly reverses theincrease in hepatic marker enzymes and total bilirubin levelsconfirming the hepatoprotective activity of this plant [1]

39 Other Activities The ethanol extract from Portulacaoleracea at a concentration range of 100 200 and 400mgkgrespectively displays a dose-dependent effect in prolongingthe survival time of mice in hypoxic models including closednormobaric hypoxia and potassiumcyanide or sodiumnitritetoxicosisThis extract also enhances the activities of phospho-fructokinase pyruvate kinase and lactate dehydrogenase inglycolysis and the level of adenosine triphosphate of mousecortices in hypoxia models [12] The preliminary woundhealing activity of Portulaca oleracea has been appraised inMus musculus JVI-1 and it has been shown that a fresh crudeextract significantly accelerates the wound healing course bythe stimulation of wound contraction and downregulation ofthe surface area of the excisionwound [10] Portulaca oleraceaalso has the ability to accumulate Se even at the shortest timespan of 42 days and hence it can perform the dual functionsof preventing the occurrence of Se deficiency linked diseasessuch as Keshan and Kashin-Beck diseases [47]

4 Conclusion

Portulaca oleracea is of considerable importance to thefood industry and also possesses a wide spectrum of phar-macological properties such as neuroprotective antimi-crobial antidiabetic antioxidant anti-inflammatory antiul-cerogenic and anticancer activities which are associatedwith its diverse chemical constituents including flavonoidsalkaloids polysaccharides fatty acids terpenoids sterolsproteins vitamins and minerals

Although bioactivities of extracts or compounds isolatedfrom Portulaca oleracea are substantiated by using in vitroand in vivo studies including animal models and cell culturestudies the mechanisms of action have not been addressedHence more mechanistic studies are required before Portu-laca oleracea can be considered for further clinical use Thisreview concludes that Portulaca oleracea is an edible and amedicinal plant which is important to the food industry andmay also have a significant role to play in health care providedthat adequate studies are conducted

Figure 1 Chemical structures of main compounds present in Portulaca oleracea

inhibition zones of 13 14 and 15mm respectively as well asantifungal activity against Candida albicans with inhibitionzone of 12mm [1]

36 Anti-Inflammatory Activity Pretreatment with the aque-ous extract of Portulaca oleracea inhibits tumor necrosisfactor- (TNF-) 120572-induced production of intracellular reac-tive oxygen species (ROS) and overexpression of intercel-lular adhesion molecule- (ICAM-) 1 vascular cell adhesionmolecule (VCAM)-1 and E-selectin in human umbilical veinendothelial cells (HUVECs) in a dose-dependent mannerThis extract also suppresses the translocation of nuclearfactor 120581B (NF-120581B) p65 to the nucleus TNF-120572-inducedNF-120581Bbinding and the degradation of inhibitor molecule (I120581B)120572Furthermore an inhibition in the adhesion of HL-60 cellsto TNF-120572-induced HUVECs and TNF-120572-induced mRNAexpression of interleukin- (IL-) 8 andmonocyte chemoattrac-tant protein- (MCP-) 1 is also observed The aqueous extractof Portulaca oleracea may also play an important role in thesuppression of the vascular inflammatory process related tothe development of atherosclerosis [46]

37 Antiulcerogenic Activity Aqueous and ethanolic extractsof Portulaca oleracea at 08 gkg and 14 gkg respectively canreduce the severity of HCl-induced gastric ulcers in a dose-dependent manner this is comparable to the effect observedwith sucralfate 01 gkg In addition the aqueous extract (056and 08 gkg) and the ethanolic extract (08 and 14 gkg)display suppression of lesions induced by absolute ethanolThe oral and intraperitoneal doses of both extracts dose-dependently increase the pH of gastric juice in mice withpylorus ligationThus Portulaca oleracea holds great promiseas an effective therapeutic agent for gastrointestinal diseasesdue to its gastroprotective activity [7]

38 Hepatoprotective Activity Intraperitoneal administra-tion of CCl

4elicits liver injury in rats which notably upreg-

ulates the levels of total bilirubin and serum hepatic markerenzymes including glutamate pyruvate transaminase (GPT)and glutamate oxaloacetate transaminase (GOT) A 70alcohol extract of Portulaca oleracea significantly reverses theincrease in hepatic marker enzymes and total bilirubin levelsconfirming the hepatoprotective activity of this plant [1]

39 Other Activities The ethanol extract from Portulacaoleracea at a concentration range of 100 200 and 400mgkgrespectively displays a dose-dependent effect in prolongingthe survival time of mice in hypoxic models including closednormobaric hypoxia and potassiumcyanide or sodiumnitritetoxicosisThis extract also enhances the activities of phospho-fructokinase pyruvate kinase and lactate dehydrogenase inglycolysis and the level of adenosine triphosphate of mousecortices in hypoxia models [12] The preliminary woundhealing activity of Portulaca oleracea has been appraised inMus musculus JVI-1 and it has been shown that a fresh crudeextract significantly accelerates the wound healing course bythe stimulation of wound contraction and downregulation ofthe surface area of the excisionwound [10] Portulaca oleraceaalso has the ability to accumulate Se even at the shortest timespan of 42 days and hence it can perform the dual functionsof preventing the occurrence of Se deficiency linked diseasessuch as Keshan and Kashin-Beck diseases [47]

4 Conclusion

Portulaca oleracea is of considerable importance to thefood industry and also possesses a wide spectrum of phar-macological properties such as neuroprotective antimi-crobial antidiabetic antioxidant anti-inflammatory antiul-cerogenic and anticancer activities which are associatedwith its diverse chemical constituents including flavonoidsalkaloids polysaccharides fatty acids terpenoids sterolsproteins vitamins and minerals

Although bioactivities of extracts or compounds isolatedfrom Portulaca oleracea are substantiated by using in vitroand in vivo studies including animal models and cell culturestudies the mechanisms of action have not been addressedHence more mechanistic studies are required before Portu-laca oleracea can be considered for further clinical use Thisreview concludes that Portulaca oleracea is an edible and amedicinal plant which is important to the food industry andmay also have a significant role to play in health care providedthat adequate studies are conducted

Figure 1 Chemical structures of main compounds present in Portulaca oleracea

inhibition zones of 13 14 and 15mm respectively as well asantifungal activity against Candida albicans with inhibitionzone of 12mm [1]

36 Anti-Inflammatory Activity Pretreatment with the aque-ous extract of Portulaca oleracea inhibits tumor necrosisfactor- (TNF-) 120572-induced production of intracellular reac-tive oxygen species (ROS) and overexpression of intercel-lular adhesion molecule- (ICAM-) 1 vascular cell adhesionmolecule (VCAM)-1 and E-selectin in human umbilical veinendothelial cells (HUVECs) in a dose-dependent mannerThis extract also suppresses the translocation of nuclearfactor 120581B (NF-120581B) p65 to the nucleus TNF-120572-inducedNF-120581Bbinding and the degradation of inhibitor molecule (I120581B)120572Furthermore an inhibition in the adhesion of HL-60 cellsto TNF-120572-induced HUVECs and TNF-120572-induced mRNAexpression of interleukin- (IL-) 8 andmonocyte chemoattrac-tant protein- (MCP-) 1 is also observed The aqueous extractof Portulaca oleracea may also play an important role in thesuppression of the vascular inflammatory process related tothe development of atherosclerosis [46]

37 Antiulcerogenic Activity Aqueous and ethanolic extractsof Portulaca oleracea at 08 gkg and 14 gkg respectively canreduce the severity of HCl-induced gastric ulcers in a dose-dependent manner this is comparable to the effect observedwith sucralfate 01 gkg In addition the aqueous extract (056and 08 gkg) and the ethanolic extract (08 and 14 gkg)display suppression of lesions induced by absolute ethanolThe oral and intraperitoneal doses of both extracts dose-dependently increase the pH of gastric juice in mice withpylorus ligationThus Portulaca oleracea holds great promiseas an effective therapeutic agent for gastrointestinal diseasesdue to its gastroprotective activity [7]

38 Hepatoprotective Activity Intraperitoneal administra-tion of CCl

4elicits liver injury in rats which notably upreg-

ulates the levels of total bilirubin and serum hepatic markerenzymes including glutamate pyruvate transaminase (GPT)and glutamate oxaloacetate transaminase (GOT) A 70alcohol extract of Portulaca oleracea significantly reverses theincrease in hepatic marker enzymes and total bilirubin levelsconfirming the hepatoprotective activity of this plant [1]

39 Other Activities The ethanol extract from Portulacaoleracea at a concentration range of 100 200 and 400mgkgrespectively displays a dose-dependent effect in prolongingthe survival time of mice in hypoxic models including closednormobaric hypoxia and potassiumcyanide or sodiumnitritetoxicosisThis extract also enhances the activities of phospho-fructokinase pyruvate kinase and lactate dehydrogenase inglycolysis and the level of adenosine triphosphate of mousecortices in hypoxia models [12] The preliminary woundhealing activity of Portulaca oleracea has been appraised inMus musculus JVI-1 and it has been shown that a fresh crudeextract significantly accelerates the wound healing course bythe stimulation of wound contraction and downregulation ofthe surface area of the excisionwound [10] Portulaca oleraceaalso has the ability to accumulate Se even at the shortest timespan of 42 days and hence it can perform the dual functionsof preventing the occurrence of Se deficiency linked diseasessuch as Keshan and Kashin-Beck diseases [47]

4 Conclusion

Portulaca oleracea is of considerable importance to thefood industry and also possesses a wide spectrum of phar-macological properties such as neuroprotective antimi-crobial antidiabetic antioxidant anti-inflammatory antiul-cerogenic and anticancer activities which are associatedwith its diverse chemical constituents including flavonoidsalkaloids polysaccharides fatty acids terpenoids sterolsproteins vitamins and minerals

Although bioactivities of extracts or compounds isolatedfrom Portulaca oleracea are substantiated by using in vitroand in vivo studies including animal models and cell culturestudies the mechanisms of action have not been addressedHence more mechanistic studies are required before Portu-laca oleracea can be considered for further clinical use Thisreview concludes that Portulaca oleracea is an edible and amedicinal plant which is important to the food industry andmay also have a significant role to play in health care providedthat adequate studies are conducted
