　　What is Grape Skin Extract resveratrol?Resveratrol is a naturally occurring phytoalexin produced by some higher plants in response to injury or fungal infection. Phytoalexins are chemical substances produced by plants as a defense against infection by pathogenic microorganisms, such as fungi. Alexin is from the Greek, meaning to ward off or to protect. Resveratrol may also have alexin-like activity for humans. Epidemiological, in vitro and animal studies suggest that a high resveretrol intake is associated with a reduced incidence of cardiovascular disease, and a reduced risk for cancer.In grape, resveratrol is a phytoalexin produced against the growth of fungal pathogens such as Botrytis cinerea. Its presence in Vitis vinifera grapes can also be constitutive, with accumulation in ripe berries of different levels of bound and free resveratrols, according to the genotype. In grapes, resveratrol is found primarily in the skin, and, in muscadine grapes, also in the seeds. The amount found in grape skins also varies with the grape cultivar, its geographic origin, and exposure to fungal infection. The amount of fermentation time a wine spends in contact with grape skins is an important determinant of its resveratrol content.
