melilotosides A1, B1, and C1, and non-glycosylated soyasapogenol B were isolated from Melilotus officinalis (L.) Pall. (Fabaceae) roots. The structures of the glycosides were proved using chemical transformations and spectral data. Melilotoside A1 is soyasapogenol B 3-O-β-Dxylopyranoside; melilotoside B1, soyasapogenol B 3-O-[β-D-galactopyranosyl-(1-2)-f-D-xylopyranoside]; melilotoside C1, soyasapogenol B 3-O
从 Melilotus officinalis (L.) Pall 中分离出三种新的三萜齐墩果苷、苜蓿苷 A1、B1 和 C1,以及非糖基化大豆皂醇 B。(豆科)根。使用化学转化和光谱数据证明了糖苷的结构。苜蓿苷 A1 是大豆皂醇 B 3-O-β-吡喃木糖苷;苜蓿苷 B1,大豆皂苷 B 3-O-[β-D-吡喃半乳糖基-(1-2)-fD-吡喃木糖苷];melilotoside C1, soyasapogenol B 3-O-[α-L-rhamnopyranosyl-(1-2)-β-D-galactopyranosyl(1-2)-β-Dxylopyranoside]。
