Three triterpenoid saponins, gymnocladus saponins A (12), B (18) and C (20), were isolated from the fruits of Gymnocladus chinensis BAILLON (Leguminosae). On the basis of chemical and physicochemical evidence, these saponins were characterized as 2β, 23-dihydroxy-3-O-[α-L-arabinopyranosyl (1→6)-β-D-glucopyranosyl] acacic acid 28, 21-lactone (12), 2β, 23-dihydroxy-3-O-[β-D-glucopyranosyl (1→2)-β-D-glucopyranosyl] acacic acid 28, 21-lactone (18) and 2β, 23-dihydroxy-3-O-[β-D-xylopyranosyl (1→2)-α-L-arabinopyranosyl (1→6)-β-D-glucopyranosyl] acacic acid 28, 21-lactone (20).
