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,
