Active Ingredient Gypenosides Part used Whole Herb Apperarance White fine powder Product Content Gypenosides 98%min Test Mothed UV Product Origin Gynostemma pentaphllum (Thunb. )Mak. Action and Uses The action of gypenosides (GP, saponins of Gynostemma pentaphyllum, a Chinese medicinal herb) as an antioxidant was studied using various models of oxidant stress in phagocytes, liver microsomes and vascular endothelial cells. The results show that GP decreased superoxide anion and hydrogen peroxide content in human neutrophils and diminished chemiluminescent oxidative burst triggered by zymosan in human monocytes and murine macrophages. The extensive antioxidant effect of GP may be valuable to the prevention and treatment of various diseases such as atherosclerosis, liver disease and inflammation.
