title: [Studies on the chemical constituents from petroleum ether portion of Abelmoschus esculentus].
abstract: 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).
  
  
  CONCLUSIONS
  Compounds 1-10 are obtained from the plant for the first time and also from the genu for the first time.
