Abstract:This study was conducted to comparatively evaluate antioxidant activity of five species of Epimedium genus (Epimedium koreanum, E. brevicornum, E. pubescens, E. sagittatum and E. wushanense) and their protective effects on neuronal PC12 cells. The contents of individual penylflavonoids in five Epimedium species were also examined using HPLC/DAD. Five Epimedium plants were composed of icariin, icariside I, II, icaritin and epimedin A-C. Icariin was most predominant among all detected prenylflavonoids at all spe… Show more
