Grape is known to have a naturally existing compound known as resveratrol, which is found in the skin of red grapes and also in
Japanese knotwood plant. The phytochemical resveratrol (3, 5, 4’-transhydroxystilbene) is one of the most widely studied
representatives of the plant-produced polyphenols. As a component of grape skin (up to 0.1% ), it is extracted, along with the
coloured anthocyanins during red wine fermentation. The health multiple beneficial effects of red wine includes anticarcinogenic
effect and effects on low-density lipoproteins, is believed to result from its high concentration of polyphenols, including
resveratrol. Resveratrol has been claimed to be an activator of Sirtuin1 a gene responsible for aging. Hence an effort has been
made to study the details of it in the model organisms such as S. cerevisiae and bacteria.
