Abstract
UV radiations are principal causes of skin cancer and aging.
Suntan creams were developed to protect epidermis and derma layers
against photodegradation and photooxidation. The addition of
antioxidant plant extracts (i.e. essential oil) to sunscreens is
habitually performed, to increase their UV protective effects and
to contrast pro-radical and cytotoxic compounds present in these
solutions. According to these observations, in the present work,
the alteration of chemical composition and bioactive properties
ofLavandula angustifoliaMiller essential oil, exposed to UV light,
was investigated. UV induced a significant deterioration of
lavender oil biochemical profile. Moreover, the antioxidant
activity of this solution, inin vitrotests and directly on B16-F10
melanoma cells, greatly decreased after UV treatment. Our results
also showed that essential oil was shielded from UV stress by
propolis addition. Even after UV treatment, bee glue highly
protected lavender oil secondary metabolites from degradation and
also preserved their antiradical properties, both inin
vitroantioxidant assays and in cell oxidative damage evaluations.
This research proposed propolis as highly efficient UV protective
and antiradical additive for sunscreens, cosmetics and alimentary
or pharmaceutical products containing plant extracts.
