Abstract
Two new cycloartane-type triterpenoidal saponins, huangqiyenins A and B, were isolated from the leaves of Astragalus membranaceus BUNGE (Leg uminosae) collected in Heilongjiang Province, China, and established a s 3-O-beta-D-glucopyranosyl-(20R,24S)-16 ta,25-dihydroxy-20,24-epoxy-9 ,19-cyclolanost-6-one and 3-O-beta-D-glucopyranosyl-(24S)-16 beta,24,2 5-trihydroxy-cyclolanost-6-one, respectively, on the basis of chemical and spectral evidence.
