Abstract

Phytochemical investigation of the chloroform extract of BRYONIA ASPERA roots resulted in the isolation and structure elucidation of two new cucurbitacins (1, 2) together with eight known cucurbitane derivatives (6-13), the pentacyclic triterpene bryonolic acid (5) and two hydroxybenzoic acid amides (3, 4). Their structures were elucidated by spectroscopic analysis, including 2D NMR techniques.
