title: [GC-MS analysis of volatile constituents from Chinese eaglewood produced by artificial methods].
abstract: OBJECTIVE
  To study the volatile constituents from Chinese eaglewood samples produced by three different methods.
  
  
  METHODS
  Essential oils of the three Chinese eaglewood samples were extracted with aether at room temperature. The chemical constituents and relative contents of the volatile oils were analyzed by GC-MS.
  
  
  RESULTS
  The results showed that all the three volatile oils were mainly composed of sesquiterpenes, aromatic constituents, and fatty acids.
  
  
  CONCLUSIONS
  The quality of the three Chinese eaglewood samples was evaluated by comparison of the characteristic constituents and their contents, of them, the quality of the Chinese eaglewood samples produced by methods of nail insetting and holing was better.
