Eight new steroidal glycosides, tentatively named YS-VI, -VII, -VIII, -IX, -X, -XI, -XII and -XIII were isolated from the caudex of Yucca gloriosa along with P-1, YG-2 and YG-3 previously obtained from flowers. The structures of five of these compounds were elucidated as mexogenin 3-O-beta-D-glucopyranosyl-(1----2)-beta-D-galactopyranoside (YS-VI), gloriogenin 3-O-beta-D-glucopyranosyl-(1----2)-[beta-
8个新的甾体糖苷,暂定名为YS-VI、-VII、-VIII、-IX、-X、-XI、-XII和-XIII,以及P-1、YG-2和YG -3 以前从花中获得。其中五种化合物的结构被阐明为 mexogenin 3-O-beta-D-glupyranosyl-(1----2)-beta-D-galactopyranoside (YS-VI), gloriogenin 3-O-beta-D-吡喃葡萄糖基-(1----2)-[β-D-吡喃葡萄糖基-(1----3)]-β-D-吡喃葡萄糖苷(YS-VII)和3-O-β-D-吡喃葡萄糖基-( 1----2)-[β-D-吡喃葡萄糖基)-(1----3)]-β-D-吡喃半乳糖苷(YS-VIII),manogenin 3-O-β-lycotetraoside(YS-IX)和 3-O-α-L-rhamnopyranosyl-beta-lycotetraoside (YS-X),分别基于化学和光谱证据。
