摘要

The two trisdesmoside cycloartane glycosides astragaloside VII and cyclotrisectoside were isolated from Astragalus dissectus (Leguminosae) and identified.The latter was 20R,25-epoxy-24S-cycloartan-3 beta,6 alpha,16 beta,24-tetraol 3-O-beta-D-xylopyranoside-6,24-di-O-beta-D-glucopyranoside and was a new natural compound.
