Objective:
To study the chemical constituents of Abelmoschus esculentus.
Methods:
The 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 date.
Results:
Twelve compounds were isolated and identified as 9,19-23 (Z)-cycloart-23-en-3beta, 25-diol(1), ergost-7,22-diene-3beta,5alpha,6beta-triol(2),5alpha, 6alpha-epoxyergost-8(14), 22-dien-3beta, 7alpha-diol(3), 5alpha,8alpha-epidioxyergost-22-en-3beta-ol(4), stigmast-5-ene-3beta,7alpha-diol(5), stigmast-5, 22-diene-3beta,7alpha-diol(6), stigmast-4-en-3beta,6beta-diol(7), stigmast-4,22-diene-3beta,6beta-diol(8), stigmast-4-ene-3, 6-dione(9), stigmast-4-ene-3-one (10),beta-sitosterol(11), daucosterol(12).
Conclusion:
Compounds 1-10 are obtained from the plant for the first time and also from the genu for the first time.
