Two new bidesmoside triterpenoid saponins which were identifed as 28-O-β-Dxylopyranosyl(1→3)-β-D-xylopyranosyl(1→4)-α-L-rhamnopyranosyl(1→2)-[α-L-rhamnopyranosyl(1→3)]-β-D-fucopyranosyl gypsogenin 3-O-β-D-glucopyranosyl (1→2)-β-Dglucopyranosiduronic acid (C1) and 28-O-β-D-xylopyranosyl(1→4)-α-L-rhamnopyranosyl (1→2)-[α-L-rhamnopyranosyl(1→3)]-β-D-fucopyranosyl gypsogenin 3-O-β-D-glucopyranosyl(1→2)-β-D-glucopyranosiduronic acid (C2) were isolated together with two known compounds from the seeds
