Abstract:
OBJECTIVETo study the chemical constituents of Excoecaria agallocha L.
METHODThe constituents were isolated and purified by repeated column chromatography and their structures were elucidated by spectroscopic analysis.
RESULTSix 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.
CONCLUSIONCompounds 5-8 were isolated from E. agallocha for the first time.
