title: [Chemical constituents of ethyl acetate fraction from Aeschynanthus bracteatus].
abstract: OBJECTIVE
  To study the constituents of EtOAc extract from Aeschynanthus bracteatus.
  
  
  METHODS
  The constituents were isolated and purified by chromatography on silica gel and the structures of the compounds were determined by MS and NMR spectral analysis.
  
  
  RESULTS
  On the basis of spectroscopic analysis and comparison with the reported data, compounds were identified as koaburaside (1), coniferaldehyde (2), syringaldehyde (3), sinapinaldehyde (4), 2,4'-dihydroxyacetophenone (5), piceol (6), beta-daucosterol (7), beta-sitosterol (8).
  
  
  CONCLUSIONS
  Compounds 1 and 2 are obtained from this genus for the first time.
