Abstract

A new flavonol glycoside named epimedin K was isolated from the aerial parts of Epimedium koreanum NAKAI (Berberidaceae). Its chemical structure was found to be anhydroicaritin 3-O-β-D-(2, 6-di-O-acetyl) glucopyranosyl (1→3)-α-L-(4-O-acetyl) rhamnopyranoside-7-O-β-D-glucopyranoside on the basis of spectroscopic and chamical evidence.
