ABSTRACT

Another two methylsteroids of the cycloartane series have been isolated from the epigeal part ofAstragalus alopecurus. The structures of the compounds isolated, cycloalpigenin and cycloalpioside, have been established as (20R,24R)-16β,24:20, 24-diepoxycycloartane-3β,7β,25-triol and (20R,24R)-16β, 24:20,24-diepoxycycloartane-3β,7β, 25-triol 3-O-β-D-xylopyranoside, respectively, on the basis of chemical transformations and spectral characteristics. The structure of cycloalpigenin has been confirmed by chemical correlation with that of cycloalpigenin D. More... »
