title: [GC-MS analysis of supercritical carbon dioxide extraction products from Rhodiola tibetica].
abstract: OBJECTIVE
  To analyze the chemical constituents of supercritical carbon dioxide extraction products from Rhodiola tibetica.
  
  
  METHODS
  The chemical constituents were separated and identified by gas chromatography-mass spectrometry (GC-MS).
  
  
  RESULTS
  26 Components were identified, and their relative contents were determined by normalization method of area.
  
  
  CONCLUSIONS
  This study provides foundation for the exploitation of the resources of R. tibetica.
