Volatile Oils

• Essential oils

• volatilize and distilled in steam

• chemically and physically different from fixed oils – not glyceryl esters of fatty acids

– do not leaves permanent grease spot in paper

– not saponified with alkali

– not become rancid but on exposure to air and light becomes oxidized and resinify

• frequently associated with other substances like gums, resins

Volatile Oils• they are secreted by oil glands, oil cells, secretory

ducts, glandular hairs, modified parenchyma cells, oil tubes (vittae), lysigenous or schizogenous passages

• Use: therapeutically - administered by inhalation (eucalyptus oil), orally (peppermint oil), gargle and mouthwash (thymol oil), transdermal (lavender, rosemary, bergamot - aromatherapy)

• with phenol content - antiseptic, carminative

(clove, thyme) antispasmodic

• anti-bacterial, food preservative

Volatile Oils

• generally mixtures of hydrocarbons and oxygenated compounds derived from hydrocarbons

• the odor and taste is mainly determined by the oxygenated constituents which is immiscible in water but more soluble in alcohol

• many of them are terpenoids in origin with some containing aromatic derivatives

Volatile Oils

• Evaluation– preliminary examination: odor and taste

• taste, if diluted with a sugar solution in ethanol as prescribed by BP)

– Physical measurements: optical rotation, relative density, refractive index

– to determine individual proportions of components - Gas Chromatography

– volatile oil content in crude drugs - determined by distillation (clavenger method)

Volatile Oils• Methods of obtaining volatile oils

1. Direct steam distillation- disadv: hydrolysis of certain components decomposition at high temperatures

2. Expression - those that cannot be distilled due to decompositiona. ecuelle methodb. sponge method

3. Enfleurage - fat absorbs oil4. Extraction - solvent systems and distilled at 50oC5. Rectification - second distillation in steam and frees oil from resin and other impurities

Volatile Oils• volatile oils’ chemical constituents are divided

into 2 classes based on their biosynthetic origin:

– 1. Terpenoid derivatives - acetate - mevalonic acid pathway

– 2. Aromatic compounds - shikimmic acid - phenyl propanoid pathway

• many volatile oils are largely monoterpenoids and others phenylterpenoids

• constituents are responsible for their characteristic odor, taste, flavor and therapeutic properties
