| Abstract: | Objective To evaluate radical scavenging and antioxidant activities of different extracts from Epimedium brevicornum Maxim. Methods The radical scavenging activity was assessed by means of 2. 2diphenyl-1-picrylhydrazyl（ DPPH） assay. The antioxidant activity was assessed by means of β-carotene bleaching test. Rusult The acetic ether extract from E. brevicornum Maxim showed significant antiradical and antioxidant effects. Conclusion The aceticether extract from E. brevicornum Moxim contains antionidant compounds,to offer evidence to drug exploiture. |
