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.
