摘要

The stems of Astragalus pycnanthus Boriss. (Leguminosae) contain a number of low-molecular-mass substances, of which β-sitosterol, cyclosieversioside F, and D-3-O-methyl-chiro-inositol have been identified, and also a new cycloartane diglycoside - 24R-cycloartane-3β,6α,16β,24,25-pentaol 16-O-β-D-glucopyranoside 3-O-β-D-xylopyranoside.
