摘要：

Fourteen chemical constituents were isolated from the CHCl3 soluble portion of the heartwood of Melaleuca leucadendron L.. These compounds include beta-sitosterol (1), beta-sitostenone (2), 6-hydroxy-4,6-dimethyl-3-hepten-2-one (3), naphthalene (4), squalene (5), 2 alpha,3 beta-dihydroxyurs-12-en-28-oic acid (6), 3 beta-hydroxylup-20(29)-en-27,28-dioic acid(7), 2 alpha,3 beta-dihydroxyolean-12-en-28-oic acid(8), 3 beta,23-dihydroxyolean-12 -en-28-oic acid (9), 2 alpha,3 beta,23-trihydroxyolean-12-en-28-oic acid (10), 3 beta-trans-p-coumaroyloxy-2 alpha,23-dihydroxyolean-12-en-28-oic acid (11), and three novel oleanane derivatives 23-trans-p-coumaroyloxy-2 alpha,3 beta-dihydroxyolean-12-en-28-oic acid (12), 3 beta-trans-caffeoyloxy-2 alpha,23-dihydroxyolean-12-en-28-oic acid (13), and its isomer 3 beta-cis-caffeoyloxy-2 alpha,23-dihydruxyolean-12-en-28-oic acid (14). The three novel compounds were characterized as the two and three O-methylated derivatives, respectively.
