Abstract

The change of icariin( ICA) content in thirty-three samples of five Epimedium species listed in the Chinese Pharmacopoeia( 2015 edition),including E. brevicornu,E. sagittatum,E. pubescens,E. koreanum,and E. wushanense has been investigated in this study. The results indicated that the optimized process procedure was baking at 150 ℃ for 30 min,and 3'''-carbonyl-2″-β-L-quinovosyl icariin( CQICA) could not be translated into ICA and ICA could be converted under this heating process condition. ICA increased remarkably after the heating process by 1-3 times in E. brevicornu,E. wushanense and E. koreanum,and increased lightly in E. brevicornum and E. pubescens,while ICA slightly increased or decreased in E. sagittatum and E. wushanense.

Keywords: 3’’’-carbonyl-2″-β-L-quinovosyl icariin; Epimedii Folium; Epimedium koreanum; change in content; heating process; icariin.
