Abstract: The extraction method of antiradical components from Gymostemma pentaphyllam was studied, and the antiradical effect of Gymostemma pentaphyllam from different areas were compared. It was found that the Gymostemma pentaphyllam with the highest antiradical activity is from Shennongjia, higer than that from Liu Zhou. Its scavenging rates to hydroxyl radical and oxygen free radical are 100% and 67% respectively, and its highest inhibition rate to nitrosamine is 51%.

Key words: Gymostemma pentaphyllam, extraction, super oxygen free radical, hydroxyl radical, nitrosamine
