The structure of a new cycloartane-type triterpene glycoside, cyclomacroside E, which was isolated from roots of Astragalus macropus Bunge (Leguminosae), was established as 3-O-α-L-rhamnopyranoside,24-O[(β-D-xylopyranosyl)(1→2)-β-D-xylopyranoside]-24R-cycloartan-1α,3β,7β,24,25-pentaol.

Ten pure compounds, three of which were identified as β-sitosterol, β-sitosterol β-D-glucopyranoside, and D-3-O-methyl-chiro-inositol, were isolated from roots of Astragalus macropus Bunge (Leguminosae). The structure of the new cycloartane triterpenoid cyclomacrogenin B was established as 24R-cycloartan-1α,3β,7β,24,25-pentaol.
