GENERAL DESCRIPTION & APPLICATIONS |
||
|
Resveratrol (3,5,4'-trihydroxystilbene) is a
non-flavonoid polyphenolics compound found highly in the skin of red grapes and
as a constituent of red wine. It is also found in teas, berries and peanuts.
Resveratrol is a compound of stilbene structure (and is responsible for the
principle coloring of the plants. Resveratrol is created by plants as a phytoalexin (plant's defense
arsenal) against bacteria
and fungi. It is marketed as a nutritional supplement that shows health-giving antioxidant effects such
as anti-cancer, antiviral, and anti-aging. Resveratrol inhibits COX-1 enzyme and
demonstrates anti-inflammatory effects. It is a platelet aggregation inhibitor
to block the adhesion of blood cells to vessel walls and therefore prevents
heart disease and cerebral apoplexy.
It exists as two structural isomers: cis- (Z)
and trans- (E), Piceatannol or 3,4,3',5'-tetrahydroxy-trans-stilbene is a phenolic that is structurally related to resveratrol. Piceatannol has one more hydroxyl group at 3' position. It is a metabolite of resveratrol and is found in red wine. Pterostilbene (3,5-Dimethoxy-4'-hydroxy-trans-stilbene) is an analog of resveratrol. The two phenolic hydroxyl groups among three are converted to methyl ethers. Some reports say that the ethers enhance antioxidant effects. |
