title: [Comparison of the chemical components of essential oil extracted by supercritical CO2 fluid and steam distillation from Pteris multifida].
abstract: OBJECTIVE
  To compare the chemical components of essential oil extracted by supercritical CO2 fluid extraction (SFE-CO2) and steam distillation extraction (SD) from Pteris multifida.
  
  
  METHODS
  The essential oil of Pteris multifida was extracted by SFE-CO2 and SD. The chemical components of essential oil were separated and analyzed by GC-MS. Their relative contents were determined by normalization of peak area.
  
  
  RESULTS
  Twenty -seven compounds in the essential oil extracted by SFE-CO2 and 45 compounds in the essential oil extracted by SD were identified respectively. There were 11 common components.
  
  
  CONCLUSIONS
  The chemical components of essential oil extracted by SFE-CO2 are different from that extracted by SD.
