Abstract

A novel prenylflavonol glycoside, named acetylicariin, has been isolated from the aerial parts of Epimedium koreanum Nakai. The structure has been identified by electrospray ionization multi-stage tandem mass spectrometry (ESI-MSn) and other chemical evidence, which has been elucidated as 8-prenylkaempferol-4'-methoxyl-3-O-alpha-L-rhamnopyranosyl-7-O-beta-D-(2"-O-acetyl)glucopyranoside.

摘要

从朝鲜淫羊藿地上部分分离出一种新型的异戊烯基黄酮醇苷，命名为乙酰淫羊藿苷。其结构已通过电喷雾电离多级串联质谱（ESI-MSn）及其他化学证据得以鉴定，结构被阐明为8-异戊烯基山奈酚-4'-甲氧基-3-O-α-L-鼠李糖基-7-O-β-D-（2''-O-乙酰基）葡萄糖苷。
