title: [Comparison study of different methods for extracting volatile oil from bergamot].
abstract: OBJECTIVE
  To test different methods for extracting volatile oil from bergamot.
  
  
  METHODS
  The determination of bergapten was carried out by RP-HPLC. Four different ways of organic solvent extraction, steam-input distillation, distillation of the material mixed with water and press extraction were compared.
  
  
  RESULTS
  Bergapten wasnt extracted by ways of steam-input distillation and distillation of the material mixed with water.
  
  
  CONCLUSIONS
  The steam distillation extraction can be taken to extract volatile oil from bergamot for protecting humans' skins.
