[Structure determination of korepimedoside A and korepimedoside B from Epimedium koreanum Nakai].
Two new flavonol glycosides were isolated from the aerial parts of Epimedium koreanum Nakai. On the basis of spectroscopic and chemical evidence, they were elucidated as anhydroicaritin 3-O-beta-D-(6-acetyl) glucopyranosyl (1-->3)-alpha-L-(4-acetyl) rhamnopyranoside and anhydroicaritin 3-O-beta-D-(2, 6-diacetyl) glucopyranosyl (1-->3)-alpha-L-(4-acetyl) rhamnopyranoside-7-O-beta-D-glucopyranoside, which were named korepimedoside A and korepimedoside B respectively.
