Further Saponins and Flavonoids from Astragalus verrucosus Moris.

From the aerial parts of Astragalus verrucosus Moris, a novel cycloartane-type triterpene glycoside, named astraverrucin VII, was isolated along with cycloaraloside D (peregrinoside II) and cycloaraloside C (astrailienin A). The flavonoid composition was investigated for the first time, and fifteen known flavonoids were isolated and identified. All structural elucidation were performed by spectral means. The chemiotaxonomic importance of these findings is discussed. [ABSTRACT FROM AUTHOR]
