Active Ingredient:Trans-Resveratrol CAS No.:501-36-0 Structural formula: ..................................................................................................................................... Description Plant origin Resveratrol mainly comes from the dry roots of Polygonum cuspidatum Sieb . Et Zucc.,the fruit skins and seed of grape(Vitis vinifera ) , the seeds of peanut(Arachis hypogaea) etc
Physical property Resveratrol is tasteless white crystal (methanol); Soluble in water, ethanol, acetone, etc.Melting point of 253-255 centigrade , sublimation point of 261 centigrade.
Stability This product can produce fluorescence under UV irradiation, when pH > 10, the stability ispoorer. When meet ferric chloride and potassium ferricyanide solution, it reveals blue, whenencounter alkaline solutions such as ammonia water,it appears red. Resveratrol is unstable to light. Huachengbio stability test shows, high purity resveratrol ethanol solution in darkness can only be stable for few days, so,they suggest that it would be better to prepare the substance solutions and sample solution according to the need when do resveratrol content analysis.
Isomer Resveratrol in natural conditions exist with two forms of free state and glycosidase catalysed .They respectively have two isomers,cis and trans. Namely the cisregulatory resveratrol (cisRes), trans resveratrol (transRes) resveratrol PD (cisPD), trans resveratrol PD (transPD). The after two forms releaseresveratrol under the enzyme action on intestinal system . Resveratrol in plants mainly exist with trans form .Rresearch shows that the physiological activity of trans isomers is better than the cis isomers.
Pharmacological effects Resveratrol is a natural antioxidant,.It can reduce blood viscosity, inhibit platelet condensationand diastolic blood vessels, keep the blood flowing; can prevent the occurrence of cancer and development; has prevention and cure function on atherosclerosis and coronary heart disease, ischemic heart disease, high blood lipid ;can inhibit tumor. It has estrogenic effect, can be used in the treatment of breast cancer and other diseases. .....................................................................................................................................
