Triterpenoid saponins from Sophora subprostrata.
From Sophora subprostrata Radix, the roots of Sophora subprostrata, six triterpenoidal saponins having soyasapogenol A, B, sophoradiol and kuzusapogenol A as aglycones, were isolated as their methyl esters. The structure of a new saponin was established to be 3-O-[alpha-L-rhamnopyranosyl(1----2)-D-galactopyranosyl(1----2)-beta-D- glucuronopyranosyl] kuzusapogenol A methyl ester by means of 1H and 13C NMR spectroscopy and chemical evidence.
