A newtriterpene glycoside of the cycloartane series (cycloaraloside C) has been isolated from the roots of the plantAstragalus amarus Pall. (Leguminosae). Cycloaraloside C is a bioside of cyclosieversigenin including one D-glucose residue and one D-apiose residue. The structure of the glycoside has been shown on the basis of the chemical transformations and spectral characteristics as 20R,24S-epoxycycloartane-3β
