ABSTRACT

Eight compounds of triterpenoid nature have been isolated from the epigeal parts of the plantAstragalus alopecurus Pall. (Leguminosae) and have been designated in order of increasing polarity as substance 1–8. On the basis of chemical transformations and spectral characteristics, we have established the structures of 4 and 8, which have been called cycloalpigenin D and cycloalpioside D, respectively. Cycloalpigenin D is 20R,24S-epoxycycloartane-3β,7β,16β,25-tetraol. Cycloalpioside D is cycloalpigenin D 3-O-β-D-xylopyranoside. More... »
