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-α-L-rhamnopyranosyl-(1→2)-β-D-xylopyranosyl-(1→2)-β-D-glucuronopyranosyl yunganogenin C 21-O-β-D-glucopyranoside (1), 3-O-α-L-rhamnopyranosyl-(1→2)-β-D-galactopyranosyl-(1→2)-β-D-glucuronopyranosyl yunganogenin C 21-O-β-D-glucopyranoside (2), 3-O-α-L-rhamnopyranosyl-(1→2)-β-D-xylopyranosyl-(1→2)-β-D-glucuronopyranosyl wistariasapogenol B 30-O-β-D-glucopyranoside (3), 3-O-α-L-rhamnopyranosyl-(1→2)-β-D-xylopyranosyl-(1→2)-β-D-glucuronopyranosyl wistartiasapogenol A 30-O-β-D-glucopyranoside (4) and 3-O-β-galactopyranosyl-(1→2)-β-D-glucuronopyranosyl wistariasapogenol A 30-O-β-D-glucopyranoside (5), respectively.
