Two new triterpenoid glycosides, 3-O-α-L-rhamnopyranosyl-(1→2)-β-D-galactopyranosyl-(1→2)-β-D-glucuronopyranosiduronic acids (2 and 3) of 3β, 22β-dihydroxyolean-12-en-29-oic acid and 3β, 21β, 22β-trihydroxyolean-12-en-29-oic acid, along with a known glycoside, kaikasaponin III (1), were isolated from the bark of Dalbergia hupeana HANCE. Their structures were determined by chemical and spectral methods.
