title: [Studies on chemical constituents of leaves of Aquilaria sinensis].
abstract: OBJECTIVE
  To investigate the chemical constituents of the leaves of Aquilaria sinensis, and provide a certain of basis for the comprehensive uses of the plant of A. sinensis.
  
  
  METHODS
  The chemical constituents were isolated by various column chromatographic method. The structures were identified by spectral analyses of NMR, MS, et al.
  
  
  RESULTS
  Thirteen compounds were isolated and identified as 7-hyroxy-5, 4'-dimethoxy flovone (1), 5-hydroxy-7, 4'-dimethoxy flavone (2), luteolin-7-3',4'-trimethyl (3), isocorydine (4), 4-hydroxybenzoic acid (5), triacontenoic (6), hentriacontane (7), alpha-stigmasterol (8), epifriedelanol (9), friedelan (10), friedelin (11), genkwanin (12), 5, 4'-dihyroxy-7, 3'-dimethoxy flovone (13).
  
  
  CONCLUSIONS
  Compound 4 was obtained from this genus for the first time, compounds 1, 6-11, 13 were obtained from this species for the first time.
