Resveratrol is a phytolexin produced naturally by several plants when under attack by pathogens such as bacteria or fungi. Resveratrol has also been produced by chemical synthesis and is sold as a nutritional supplement derived primarily from Japanese knotweed.

Resveratrol is found in the skin of red grapes. It is a vital constituent of red wine but not available in a very good amount in red wine. Though, it is very concentrated in proportion. It is treated often as the best French secret. French people are blessed with glowing blemish free skin because of this amazing ingredient of red wine. It has been shown in the researches that resveratrol can also extend the life of skin cells.

Resveratrol is the reason for the glowing skin of the French. French, who ate unhealthy amounts of oily foods had the decreased rate of heart disease and related illness in the western world. The solution was found in the red wine they were drinking, to be very prcised, in the resveratrol found in the red wine.

The Benefits include:

2. Triggering and supporting the immune system and helping to wrestle off illness and colds.

Resveratrol is found in the skin of red grapes and is a constituent of red wine, but apparently not in sufficient amounts to explain the French paradox. Experiments have shown that resveratrol treatment extended the life of fruit flies, nematode worms and short living fish, but it did not increase the life span of mice.

Resveratrol chemically is a polyphenolic phytolexin ( 3,5,4- trihydroxystilbene). It is a derivative of stilbene, and produced in plants as result of the action of stilbene synthase.

It exists in two isomeric form cis(Z) and Trans (E), It exists as two geometric isomers: cis- (Z) and trans- (E). The trans- form can undergo isomerization to the cis- form when exposed to ultraviolet irradiation.

Trans resbveratrol is a very stable compound with accelerated stability conditions of 75% humidity and 40 degrees C in normal air pressure. Resveratrol content also stayed stable in the skins of grapes and pomace taken after fermentation and stored for a long period.
