Abstract

Phytochemical study of the leaves of Eugenia dysenterica led to the identification of five pentacyclic triterpenes: urs-12-en-3β-ol (α-amyrin), olean-12-en-3β-ol (β-amyrin), neolup-12-en-3β-ol (neolupenol), gammacer-16-en-3β-ol and D-friedoolean-14-en-3β-ol (taraxerol). Their identification was based mainly on mass spectra, 1H and 13C NMR. Pentacyclic triterpenes have not been reported before in the literature as constituents of E. dysenterica.
