Abstract

The structures of the new cycloartane triterpenoid cycloalpigenin C and its glycoside cycloalpioside C, isolated from the epigeal pan of Astragalus alopecurus Pall. (Leguminosae), have been determined. Cycloalpigenin C is 20R, 24S-epoxycycloartane-3β,12β,16β, 25-tetraol, and cycloalpioside C is the 3-O-β D-xylopyranoside of cycloalpigenin C.
