Zenex Organic Resveratrol Powder – Polygonum Cuspidatum Extract Powder Pack of 100 Gram

Resveratrol powder, a non flavonoid polyphenol organic compound, is an antitoxin produced by many plants when stimulated. Its chemical formula is c14h12o3. It can be synthesized in grape leaves and grape skins. It is a bioactive ingredient in wine and grape juice. It is easily absorbed orally and excreted in urine and feces after metabolism. In vitro and animal experiments show that resveratrol has antioxidant, anti-inflammatory, anticancer and cardiovascular protective effects.

Resveratrol powder (3-4′-5-trihydroxystilbene) is a non flavonoid polyphenol compound, whose chemical name is 3,4′, 5-trihydroxy-1,2-diphenylethylene (3,4′, 5-stilbene), molecular formula is c14h12o3, molecular weight is 228.25. The pure product of resveratrol is white to light yellow powder, tasteless, poorly soluble in water, easily soluble in ether, chloroform, methanol, ethanol, acetone, ethyl acetate and other organic solvents, melting point 253 ~ 255 ℃, sublimation temperature 261 ℃. It can show red color with alkaline solution such as ammonia water, and can produce color reaction with ferric chloride potassium ferricyanide. Resveratrol can be identified by using this property.

Natural resveratrol has CIS and trans structures. In nature, it mainly exists in trans conformation. The two structures can be combined with glucose to form CIS and trans resveratrol glycosides. The CIS and trans resveratrol glycosides can release resveratrol under the action of glycosidases in the intestine. Under UV irradiation, trans resveratrol can be converted into cis isomers.
