In a continuing study on the ingredients of Lupinus genus, we examined the oligoglycoside constituents of the Russell lupine (L. polyphyllus x L. arboreus hybrid). Five new oleanene glycosides, called Lupinosides PA1-5 (1-5), together with three known ones were isolated. Their structures of 1-5 were determined to be 3-O-alpha-L-rhamnopyranosyl-(1-->2)-beta-D-galactopyranosyl- (1-->2)-beta-D-glucuronopyranosyl soyasapogenol A 21-O-beta-D- xylopyranoside (1), 3-O-beta-D-galactopyranosyl-(1-->2)-beta-D-glucuronopyranosyl soyasapogenol A 21-O-beta-D-xylopyranoside (2), 3- O-alpha-L-rhamnopyranosyl-(1-->2)-beta-D-galactopyranosyl-(1-->2)-beta-D -glucuronopyranosyl kudzusapogenol A 21-O-beta-D- xylopyranoside (3), 3-O-alpha-L-rhamnopyranosyl-(1-->2)-beta-D- galactopyranosyl-(1-->2)-beta-D-glucuronopyranosyl soyasapogenol B 22-O-alpha-L-rhamnopyranoside (4), and 3-O-alpha-L-rhamnopyranosyl-(1-->2)- beta-D-galactopyranosyl-(1-->2)-beta-D-glucuronopyranosyl soyasapogenol B 22-O- beta-D-glucopyranosyl-(1-->4)-alpha-L-rhamnopyranoside (5), respectively.
在一项对羽扇豆属植物成分的持续研究中，我们检测了鲁塞尔羽扇豆（多叶羽扇豆×乔木羽扇豆杂交种）中的低聚糖成分。分离出了5种新的齐墩果烷糖苷，称为羽扇豆苷PA1 - 5（1 - 5），以及3种已知的糖苷。确定1 - 5的结构分别为3 - O-α-L-鼠李糖基-（1→2）-β-D-吡喃半乳糖基-（1→2）-β-D-吡喃葡糖醛酸基大豆皂醇A 21 - O-β-D-吡喃木糖苷（1）、3 - O-β-D-吡喃半乳糖基-（1→2）-β-D-吡喃葡糖醛酸基大豆皂醇A 21 - O-β-D-吡喃木糖苷（2）、3 - O-α-L-鼠李糖基-（1→2）-β-D-吡喃半乳糖基-（1→2）-β-D-吡喃葡糖醛酸基葛根皂醇A
