title: [Liposolubility constituents from leaves of Aquilaria sinensis].
abstract: OBJECTIVE
  To study the chemical constituents of the leaves of Aquilaria sinensis.
  
  
  METHODS
  The compounds were isolated and purified by the methods of solvent extraction and chromatographic technique, and their structures were identified on the basis of the analyses of spectral data.
  
  
  RESULTS
  Eleven compounds were obtained and identified as beta-sitosterol (1), hexacosanic acid (2), cryptotanshinone (3), 2alpha-hydroxyursane (4), dihydrotanshinone I (5), tanshinone I (6), tanshinone II(A) (7), 2alpha-hydroxyursolic acid (8), p-hydroxybenzoic acid (9), hydroquinone (10), and daucosterol (11), respectively.
  
  
  CONCLUSIONS
  All compounds except for compound 9 were isolated from the leaves of A. sinensis for the first time.
