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.

The known compound oleanolic acid (1) and anew cycloartane glycoside cyclounifolioside A (2), which has the structure 6,16-di-O-acetyl-24R-cycloartan-3beta,6alpha,16beta,24,25-pentaol 3-O-beta-D-glucopyranoside, were isolated from Astragalus unifoliolatus Bunge. The structures of the isolated compounds were established using chemical transformations and two-dimensional spectra (TOCSY, ROESY, HMBC HSQC COSY).
