Four new main saponins (canadensis-saponins 5-8) (compounds 5-8) were isolated from Solidago canadensis L. (Asteraceae). Using GC/MS, FAB-MS, and mainly 2D-NMR techniques their structures were identified as 3-O-[beta-D-glucopyranosyl(1----3)-beta-D- glucopyranosyl]-28-O-[beta-D-galactopyranosyl(1----2)-alpha-L- rhamnopyranosyl-(1----3)-beta-D-xylopyranosyl-(1----4)-[beta-D- xylopyranosyl-(1----3)]-alpha-L-rhamnopyranosyl-(1----2)-[beta-D-apio -D- furanosyl-(1----3)]-beta-D-6-deoxyglucopyranosyl-(1----)]-bayog enin(5),3-O- [beta-D-glucopyranosyl-(1----3)-beta-D-glucopyranosyl]-28-O-[beta-D- galactopyranosyl-(1----2)-alpha-L-rhamnopyranosyl-(1----3)-beta-D- xylopyranosyl-(1----4)-[beta-D-xylopyranosyl-(1----3)]-alpha-L- rhamnopyranosyl-(1----2)-[beta-D-apio-D-furanosyl-(1----3)]- arabinopyranosyl-(1----)]bayogenin(6),3-O-[beta-D-glucopy ran osyl-(1----3)- beta-D-glucopyranosyl]-28-O-[beta-D-galactopyranosyl-(1----2)- alpha-L-rhamnopyranosyl-(1----3)-beta-D-xylopyranosyl-(1----4)-[beta-D- xylopyranosyl-(1----3)]-alpha-L-rhamnopyranosyl-(1----2)-[alpha-L- rhamnopyranosyl-(1----3)]-beta-D-6-deoxyglucopyranosyl-(1----)]-++ +bayogenin (7), and 3-O-[beta-D-glucopyranosyl-(1----3)-beta-D-glucopyranosyl]-28-[O- beta-D-galactopyranosyl-(1----2)-alpha-L-rhamnopyranosyl-(1----3)-beta-D - xylopyranosyl-(1----4)-[beta-D-xylopyranosyl-(1----3)]-alpha-L- rhamnopyranosyl-(1----2)-[alpha-L-rhamnopyranosyl-(1----3)]arabinopyr anosyl - (1----)[-bayogenin (8).
从加拿大一枝黄花（菊科）中分离出4种新的主要皂苷（加拿大一枝黄花皂苷5 - 8）（化合物5 - 8）。利用气相色谱/质谱联用仪、快原子轰击质谱法以及主要的二维核磁共振技术，确定它们的结构分别为3 - O - [β - D - 吡喃葡萄糖基(1→3)-β - D - 吡喃葡萄糖基]-28 - O - [β - D - 吡喃半乳糖基(1→2)-α - L - 鼠李吡喃糖基-(1→3)-β - D - 吡喃木糖基-(1→4)-[β - D - 吡喃木糖基-(1→3)]-α - L - 鼠李吡喃糖基-(1→2)-[β - D - 芹菜糖基 - D - 呋喃糖基-(1→3)]-β - D - 6 - 脱氧吡喃葡萄糖基-(1→)]-贝萼皂苷元(5)、3 - O - [β - D - 吡喃葡萄糖基-(1→3)-β - D - 吡喃葡萄糖基]-28 - O - [β - D - 吡喃半乳糖基-(1→2)-α - L - 鼠李吡喃糖基-(1→3)-β - D - 吡喃木糖基-(1→4)-[β - D - 吡喃木糖基-(1→3)]-α - L - 鼠李吡喃糖基-(1→2)-[β - D - 芹菜糖基 - D - 呋喃糖基-(1→3)]-阿拉伯吡喃糖基-(1→)]贝萼皂苷元(6)、3 - O - [β - D - 吡喃葡萄糖基-(1→3)-β - D - 吡喃葡萄糖基]-28 - O - [β - D - 吡喃半乳糖基-(1→2)-α - L - 鼠李吡喃糖基-(1→3)-β - D - 吡喃木糖基-(1→4)-[β - D - 吡喃木糖基-(1→3)]-α - L - 鼠李吡喃糖基-(1→2)-[α - L - 鼠李吡喃糖基-(1→3)]-β - D - 6 - 脱氧吡喃葡萄糖基-(1→)]-贝萼皂苷元(7)，以及3 - O - [β - D - 吡喃葡萄糖基-(1→3)-β - D - 吡喃葡萄糖基]-28 - [O - β - D - 吡喃半乳糖基-(1→2)-α - L - 鼠李吡喃糖基-(1→3)-β - D - 吡喃木糖基-(1→4)-[β - D - 吡喃木糖基-(1→3)]-α - L - 鼠李吡喃糖基-(1→2)-[α - L - 鼠李吡喃糖基-(1→3)]阿拉伯吡喃糖基 - (1→)[-贝萼皂苷元(8)。
