Abstract

Two new pentacyclic triterpenes of the taraxastane group have beenisolated from Canarium strictum Roxb. One is a ketol and the other a diol. Chemical evidence, IR, UV, NMR spectra and their mass spectral disintegration patterns show that they are represented by the structures I and IIa. They have been named as epi-Ψ-taraxastanonol and epi-Ψ taraxastane diol respectively.
