Abstract

The aerial part of Astragalus mucidus Bunge (Leguminosae) contains several isoprenoid compounds, two of which were isolated pure. The structure of a new triterpene glycoside of the cycloartane series, cycloascidoside A, was determined as 24R-cycloartan-3β,6α,16β,24,25-pentaol-3-O-β-D-xylopyranoside-6-O-β-Dglucopyranoside. D-3-O-Methyl-chiro-inositol was also identified.
