朝藿甙A的结构

CHAOHUOSIDE A FROM THE AERIAL PARTS OF EPIMEDIUM KOREANUM NAKAI

摘要: 从朝鲜淫羊藿(Epimedium koreanum Nakai)地上部分分离得到一个新黄酮醇甙类成分:朝藿甙A(ChaohuosideA,I),经光谱分析证明,其结构为7-O-β-D-吡喃葡萄糖-脱水淫羊藿素-3-O-β-D-(3,6-O-二乙酰基)-吡喃葡萄糖-(1→3)-α-L-(4-O-乙酰基)-吡喃鼠李糖甙。

Abstract: A new flavonol glycoside was isolated from the aerial parts of Epimedium koreanum Nakai,family Berberidaceae.On the basis of physicochemical properties and spectroscopic analysis itsstructurewas elucidated as 7-O-β-D-glucopyranosyl-anhydroicaritin-3-O-β-D-(3, 6-O-diacetyl)-glucopyranosyl-(1→3)-α-L-(4-O-acetyl)-rhamnopyranoside.It is named chaohuoside A.
