Studies on the glycosides of Epimedium grandiflorum MORR. var. thunbergianum (Miq.) NAKAI.. III.

Abstract

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.
