Product Details


Resveratrol is a kind of non-flavonoid polyphenol compound that is antitoxin produced by many plants when being stimulated. It can be synthesized in grape leaves and skins and is the bioactive ingredient in wine and grape juice.

Pure resveratrol appears colorless acicular crystals, tasteless, insoluble in water, easily soluble in ether, chloroform, methanol, ethanol, acetone, ethyl acetate and other organic solvents, with a melting point of 256-258 ℃ and a sublimation temperature of 261 ℃. In case of exposure to alkaline solution such as ammonia, it turns red; and chromogenic reaction occurs if it is exposed to ferric chloride-potassium ferricyanide. This property is helpful in identification of resveratrol.

Natural resveratrol has both cis and trans structures. It mainly exists in the trans conformation in nature. Both structures may be combined with glucose to form cis and trans-resveratrol glycosides. Cis and trans-resveratrol glycosides under the action of intestinal glycosidases can release resveratrol. Under the action of UV, trans-resveratrol can be converted into cis-isomer.


Function and usage:

1、Resveratrol supplements are helpful in lowering blood pressure by increasing the production of nitric oxide.

2、Resveratrol supplements may benefit animal blood lipids. As antioxidants, they can also reduce the oxidation of LDL cholesterol.

3、Resveratrol supplements prolong the study life of the animal. However, it is unclear whether they will have any similar effect on humans.

4、As a kind of potent antioxidant and anti-inflammatory compounds, resveratrol is expected to protect the brain cells from damage.

5、Resveratrol helps mice develop insulin sensitivity better and resist diabetes complications. In the future, patients with diabetes may also benefit from the treatment with resveratrol.

6、Resveratrol may help reduce joint pain and prevent rupture of cartilages.

7、Resveratrol has shown exciting anticancer activity in test tube and animal experiments.
