SAPONINS FROM CARINIANA RUBRA (LECYTHIDACEAE)

Three triterpenoidal saponins were isolated from the stem bark of Cariniana rubra Gardner & Miers (Lecythidaceae). The saponins reported are monodesmosides and a bidesmoside derivatives from the triterpene 2alpha ,3beta ,23-trihydroxy-12-oleanen-28-oic acid (arjunolic acid). The proposed str...
