From the vines of Wisteria brachybotrys (Leguminosae), five new oleanene glycosides, called wistariasaponins YC1,2, B3 and A2,3, together with four known ones were isolated. Their structures have been elucidated to be 3-O-alpha-L-rhamnopyranosyl-(1-->2)-beta-D-xylopyranosyl-(1-->2)-beta-D- glucuronopyranosyl yunganogenin C 21-O-beta-D-glucopyranoside (1), 3-O-alpha-L-rhamnopyranosyl-(1-->2)-beta-D-galactopyranosyl-(1-->2)-beta -D- glucuronopyranosyl yunganogenin C 21-O-beta-D-glucopyranoside (2), 3-O-alpha-L-rhamnopyranosyl-(1-->2)-beta-D-xylopyranosyl-(1-->2)-beta- -D-glucuronopyranosyl wistariasapogenol B 30-O-beta-D-glucopyranoside (3), 3-O-alpha-L-rhamnopyranosyl-(1-->2)-beta-D-xylopyranosyl-(1-->2)-beta-D- glucuronopyranosyl wistartiasapogenol A 30-O-beta-D-glucopyranoside (4) and 3-O-beta-D-galactopyranosyl-(1-->2)-beta-D-glucuronopyranosyl wistariasapogenol A 30-O-beta-D-glucopyranoside (5), respectively.
从短柄紫藤（豆科）的藤蔓中，分离出了五种新的齐墩果烷糖苷，即紫藤皂苷YC1、2、B3和A2、3，以及四种已知的糖苷。它们的结构已被阐明，分别为3-O-α-L-鼠李糖基-（1→2）-β-D-木糖基-（1→2）-β-D-葡萄糖醛酸基云实苷元C 21-O-β-D-葡萄糖苷（1）、3-O-α-L-鼠李糖基-（1→2）-β-D-半乳糖基-（1→2）-β-D-葡萄糖醛酸基云实苷元C 21-O-β-D-葡萄糖苷（2）、3-O-α-L-鼠李糖基-（1→2）-β-D-木糖基-（1→2）-β-D-葡萄糖醛酸基紫藤皂苷元B 30-O-β-D-葡萄糖苷（3）、3-O-α-L-鼠李糖基-（1→2）-β-D-木糖基-（1→2）-β-D-葡萄糖醛酸基紫藤皂苷元A 30-O-β-D-葡萄糖苷（4）和3-O-β-D-半乳糖基-（1→2）-β-D-葡萄糖醛酸基紫藤皂苷元A 30-O-β-D-葡萄糖苷（5）。
