Ten new glycosides, icarisides A2-A4, B5-B7, E3, F1-F2 and G1, were isolated from the polar fraction of the water extract of Epimedium grandiflorum MORR. var. thunbergianum (MIQ.) NAKAI, together with three known glycosides, phenethyl glucoside, (Z)-3-hexenyl glucoside and blumenol C glucoside. Their structures were established on the basis of chemical evidence and spectral data.
从 Epimedium grandiflorum MORR. Var. thunbergianum (MIQ.) NAKAI 水提取物的极性部分分离出 10 种新苷,即冰片苷 A2-A4、B5-B7、E3、F1-F2 和 G1,以及 3 种已知苷,即苯乙基葡萄糖苷、(Z)-3-己烯基葡萄糖苷和 blumenol C 葡萄糖苷。根据化学证据和光谱数据确定了它们的结构。
