Antioxidation And Acne Treatment Of Polygonum Cuspidatum Extract Resveratrol
Resveratrol (3,5,4'-trihydroxy-trans-stilbene) is a natural compound found in red grape skin, polygonum cuspidatum, peanuts, blueberries and some other berries. It is a powerful antioxidant produced by some plants to protect them against environmental stresses. Antioxidants neutralize free radicals, which are believed to be the cause of aging. Japanese knotweed is the plant source with the highest resveratrol content. Polygonum cuspidatum extract as a traditional Chinese medicine is extracted from the dried rhizome and root of Polygonum cuspidatum Sieb.et Zucc. Resveratrol is one of its active components.

Product feature application
Resveratrol in 62.5 ~ 1000 g/mL range increased with increasing concentration, the clearance rate was gradually increasing trend, the concentration reached 1000 g/mL, the clearance rate of more than 82%; in 62.5 g/mL, the removal rate of more than VC and BHT still, at 125 g/mL, its removal DPPH free radical is slightly stronger than BHT.
Reductive ability of resveratrol
Resveratrol increased with mass concentration in the range of mass concentration of 3~200 g/mL, and the reducing power increased gradually. When the mass concentration was less than 25 mu g/mL, the reducing power of resveratrol was more than that of VC.
In vitro chemical experiments showed that resveratrol had strong antioxidant capacity in vitro, and its ability to scavenge free radicals was stronger than that of VC and other strong oxidants at lower mass concentration.
