Saponins from the compositae plants: structures of the saponins from Aster scaber Thunb.

Abstract

Many triterpene saponins have been isolated from plants belonging to a variety of families such as Leguminosae, Campanulaceae, Cucurbitaceae, and Araliaceae. Compositae, one of the largest families of the flowering plants, comprises more than 13,000 species, which make up more than 10% of all such plants. Nevertheless, very few plants of this family have been investigated as far as saponins are concerned.KeywordsMethyl EsterAnomeric ProtonTriterpene SaponinMethyl GlycosideAnomeric Proton SignalThese keywords were added by machine and not by the authors.
