title: [Chemical constituents from stems of Aquilaria sinensis].
abstract: OBJECTIVE
  To study the constituents from the stems of Aquilaria sinensis.
  
  
  METHODS
  The chemical constituents were isolated by various column chromatographic methods. The structures were identified by spectral analysis including NMR and MS data.
  
  
  RESULTS
  Sixteen compounds were isolated and identified as threo-buddlenol C (1), thero-ficusesquilignan A (2), erythro-buddlenol C (3), (+/-) buddlenol D (4), (-) medioresinol (5), (-) pinoresinol (6), 5'-methoxy lariciresinol (7), erythro-guaiacylglycerol-beta-coniferyl ether (8), thero-guaiacylglycerol-beta-coniferyl ether (9), herpetin (10), (+) syringaresinol (11), curuilignan (12), ciwujiatone (13), coniferyl alcohol (14), 3, 4, 5-trimethoxyphenol (15) and cucurbitacin (16).
  
  
  CONCLUSIONS
  All the compounds, except for 11-13 were obtained from A. sinensis for the first time.
