Abstract

Four new triterpenes, eupha-7,24-diene-3β,22β-diol (1), 20- taraxastene-3α,28-diol (2), 3α,27-dihydroxy-28,20β-taraxastanolide (3), and 3α-hydroxy-13(18)-oleanene-27,28-dioic acid (4) have been isolated from the heartwood of Melaleuca leucadendron. The structures and stereochemistry of 1-4 have been determined by spectroscopic analysis, with compounds 3 and 4 being investigated in the forms of their diacetate (3a) and dimethyl (4a) derivative, respectively.
