What is resveratrol:

      Resveratrol (trans-3,5,4'-trihydroxystilbene), belongs to a class of polyphenolic compounds called stilbenes , found largely in the skins of red grapes and root of Polygonum cuspidatum Sieb. et Zucc ( Japanese knotweed), is a component of Ko-jo-kon, an oriental medicine used to treat diseases of the blood vessels, heart and live.. Resveratrol is a fat-soluble compound that occurs in a trans and a cis configuration (see figure 1). Both cis- and trans-resveratrol also occur as glucosides (bound to a glucose molecule).
