OBJECTIVE: To study the chemical constituents of Excoecaria agallocha L. METHOD: The constituents were isolated and purified by repeated column chromatography and their structures were elucidated by spectroscopic analysis. RESULT: Six triterpenoids including taraxerone (1), beta-amyrin acetate (2), 3beta-[(2E,4E)-6-oxo-decadienoyloxy]-olean-12-ene (3), taraxerol (4), acetylaleuritolic acid (5), and cycloart-22-ene-3beta, 25-diol (6), and three steroids including beta-sitostenone (7), (24R)-24-ethylcholesta-4,22-dien-3-one (8), and beta-sitosterol (9) were isolated and identified from the stems and twigs of the mangrove plant E. agallocha. CONCLUSION: Compounds 5-8 were isolated from E. agallocha for the first time.
