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