Chemical and physical properties of Resveratrol

Resveratrol (3,5,4'-trihydroxystilbene) is a polyphenolic phytoalexin. It is a stilbenoid, a derivate of stilbene, and is produced in plants with the help of the enzyme stilbene synthase. It exists as two geometric isomers:cis-(Z) andtrans-(E), with thetrans-isomer shown in the top image. Thetrans-form can undergo isomerisation to thecis-form when exposed to ultraviolet irradiation.Trans-resveratrol in the powder form was found to be stable under "accelerated stability" conditions of 75% humidity and 40 degrees C in the presence of air. Resveratrol content also stayed stable in the skins of grapes and pomace taken after fermentation and stored for a long period.
