title: [Chemical constituents from wood of the Chinese Hainan mangrove-associated plant, Thespesia populnea].
abstract: OBJECTIVE
  To investigate chemical constituents of the Chinese Hainan mangrove-associated plant, Thespesia populnea.
  
  
  METHODS
  Compounds were isolated and purified with silica column chromatography, Sephadex LH-20 column chromatography and HPLC methods. Their structures were identified by physicochemical analysis, spectroscopic analysis (1H-NMR, 13C-NMR and MS), and comparison with the data of literatures.
  
  
  RESULTS
  Ten compounds were obtained and their structures were identified as Mansonone H (1), Populene A (2), 1,8-Dihydroxy-3-methoxy-6-methyl-9,10-anthraquinone (3), 1, 4, 5-Trihydroxy-3-methoxy-6-methyl-9,10-anthraquinone (4), 1, 8-Dihydroxy-3-carboxy-9, 10-anthraquinone (5), Catacerebroside B (6), beta-Sitosterol (7), beta-Daucosterol (8), Palmitic acid (9), 3-Hydroxy-13 (18) -ene-28-oleanolic acid (10), respectively.
  
  
  CONCLUSIONS
  Compounds 3-5, 10 are obtained from Thespesia populnea for the first time.
