New triterpene isolated from Eschweilera longipes (Lecythidaceae).

Patrícia M da Costa1, Mário G de Carvalho.   

Abstract

The phytochemical studies of Eschweilera longipes Miers (Lecythidaceae) have led to the identification of a new triterpene 3beta, 24-dihydroxyfriedelane, the known 1beta, 2beta, 3beta, 19beta-tetrahydroxyurs-12-en-28-oic acid (1beta-hydroxyeucaphic acid) besides the saponin sitosterol 3betaO-betaD-glucopyranoside. The structures were established from the IR, NMR and mass spectra data including 2D NMR experiments of natural substances and of the acetyl derivative of the new triterpene.
