OBJECTIVETo study the chemical constituents of Abelmoschus esculentus.

METHODThe chemical constituents were isolated and purified by chromatography on silica gel and recrystallization. The chemical structures were elucidated on the basis of physicochemical properties and spectral data.

RESULTFourteen compounds were isolated and identified as 6-hydroxy-stigmasta-4-en-3-one(1), 6-hydroxy-stigmasta4,22-dien-3-one(2), stigmasta-5-en-3-ol-7-one(3), stigmasta-5, 22-dien-3-ol-7-one(4), stigmast-5-en-3, 7-diol(5), stigmast-5, 22-dien-3, 7-diol(6), stigmast-4, 22-dien-3, 6-dione(7), stigmasta-4, 22-dien-3-one(8), ergosta-7, 22-dien-3-ol(9), cycloart-25-en-3,24-diol(10), lupeol(11), aurantiamide acetate (12), stigmasterol(13), hexadecanoic acid (14).

CONCLUSIONCompounds 1-12 are obtained from the genus Abelmoschus plant for the first time and also from the Malvaceae for the first time.
