- Cardiovascular protection
Polyphenols can reduce myocardial injury after ischemia in rats and reduce the sensitivity of the heart to ischemia reperfusion injury, which is related to the improvement of plasma antioxidant capacity
Polyphenols has inhibitory effect on the number of peripheral blood white blood cells, immune function, chromosome aberration, DNA damage and other radiation damage caused by acute and subacute 60co-gamma rays, indicating that GPC has good biological activity against radiation, and its mechanism may be related to the elimination of endogenous free radicals generated by radiation and the inhibition of lipid peroxidation.
Polyphenols protects against persistent skin damage caused by herpes simplex virus (HSV).
Polyphenols can dose-dependently inhibit rat claw edema caused by carrageenan and ear edema caused by croton oil

In 1999, Takahashi reported for the first time that glucophenol extracted from grape seeds can promote the growth of mouse hair epidermal cells in vitro.
