title: [GC-MS analysis on the volatile components of Platycladus orientalis extracted by HS-SPME and DSE].
abstract: OBJECTIVE
  To analyze the volatile components of Platycladus orientalis extracted by headspace solid phase microextraction (HS-SPME) and steam distillation-extraction (DSE).
  
  
  METHODS
  The volatile components which were extracted by DSE and analyzed by GC-MS; The HS-SPME conditions was optimized, and the volatile components were analyzed by GC-MS.
  
  
  RESULTS
  Sixty-two kinds of volatile components extracted by DSE were isolated and 50 of them were identified; Sixty-eight kinds of volatile components extracted by HS-SPME were isolated and 67 of them were identified.
  
  
  CONCLUSIONS
  Compared with DSE,HS-SPME has higher retrieval matching and sensitivity, which is more suitable for the analysis of the volatile components of P. orientalis.
