A novel flavonol glycoside was isolated from the aerial parts of Epimedium wushanense along with nine known flavonols; icariin, baohuoside-VI, rouhuoside, quercetin 3-galactoside and 3-rhamnoside, epimedoside-A, icaritin, baohuoside-I and baohuoside-II. Their structures were established by spectroscopic methods. The new compound was elucidated as 8-prenylkaempferol-4′-methylether-3-[xylosyl(1→4)rhamnoside]-7-glucoside.
