 Resveratrol (3,4',5-trihydroxystilbene) belongs to a class of polyphenolic compounds called stilbenes. Some types of plants produce resveratrol and other stilbenes in response to stress, injury, fungal infection, and ultraviolet (UV) radiation. Resveratrol is a fat-soluble compound that occurs in a trans and a cis configuration. Both cis- and trans-resveratrol also occur as glucosides (bound to a glucose molecule). Resveratrol-3-O-beta-glucoside is also called piceid. Scientists became interested in exploring potential health benefits of resveratrol in 1992 when its presence was first reported in red wine, leading to speculation that resveratrol might help explain the French Paradox. More recently, reports on the potential for resveratrol to inhibit the development of cancer and extend lifespan in cell culture and animal models have continued to generate scientific interest.

 Narrative History and Origin of Resveratrol.

 Resveratrol is an active component extracted from Huzhang(Polygonum cuspidatum)

 As early as the 1920's Dr. Johanna Brandt wrote a book proclaiming that grapes cured her of cancer. Since then it has been known that there are several beneficial substances in grapes (wine also of course) that assist in lowering cholesterol, reduce the risk of heart disease and have antioxidant abilities.

 Transresveratrol (chemical formula 3,5,4'-trihydroxy-trans-stilbene) is mainly found in the Polygonurn cuspidaturn, known as Hu-Chang ,the roots of Polygonurn cuspidaturn Sieb. et Zucc.;(Polygonurn multiflorurn Thumb. )

 Transresveratrol, (chemical formula 3,5,4'-trihydroxy-trans-stilbene), is found in any quantity in the skin of young unripe red grapes or Polygonum cuspidatum(some recent evidence suggests the skins of peanuts may be a third source). Polygonum cuspidatum produce transresveratrol to protect themselves after exposure to ultraviolet radiation, ozone or certain biologic agents. It functions as a ribonucleotide reductase inhibitor like Hydrea (Droxia, hydroxyurea), but potentially without the side effects of Hydrea.

 It should be noted that another chemical exists within the Polygonum cuspidatum that is 3,5,4'-trihydroxy-cis-stilbene and that it can also be called resveratrol. However the -cis- version is not as active as the -trans- version that we offer.

 Resveratrol is a natural compound with interest in nutritional phytotherapy, cosmetics, medical phytotherapy (as anti-tumour therapy adjuvant, anti-microbial effect on dermatophytes and some skin pathogenic bacteria), food (as antioxidant and free radical-scavenger), etc.
 Other High level source of resveratrol: grape skin,mulberry,Yucca schidigera (endemic agavaceous plant in some desert regions),etc.
