Chemical Constituents From the Roots of Streptocaulon Juventas

Abstract

Three cardenolides were isolated from the root of Streptocaulon juventas Merr. Their strutures were elucidated by their spectral data. A new cardenolide derivative named acovenosigenin A 3-O-glucosid from the metanol extract of the root of Streptocaulon juventas Merr.
