Abstract
A new saponin, 3-O-[a-L-rhamnopyranosyl(1→2)-β-D-glucopyranosyl(1→2)-β-D-glucuronopyranosyl]soyasapogenol B carboxylate (6) has been isolated from the medicinal plant yellow sweetclover together with azukisaponin II(7), robinin(8), and clovin(9). 7, 8, and9 are reported for the first time from this plant. The new saponin(6) exhibited inhibitory action on leucocyte migration in inflammation.
