Abstract

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.

摘要

从朝鲜淫羊藿地上部分分离得到两个新的黄酮醇苷。基于光谱和化学证据，它们被鉴定为脱水淫羊藿素3 - O - β - D -（6 - 乙酰基）吡喃葡萄糖基（1→3）- α - L -（4 - 乙酰基）吡喃鼠李糖苷和脱水淫羊藿素3 - O - β - D -（2,6 - 二乙酰基）吡喃葡萄糖基（1→3）- α - L -（4 - 乙酰基）吡喃鼠李糖苷 - 7 - O - β - D - 吡喃葡萄糖苷，分别命名为朝鲜淫羊藿苷A和朝鲜淫羊藿苷B。
