title: [Study on ingredients of essential oils of Curcuma wenyujin extracted by supercritical-CO2 fluid extraction and steam distillation].
abstract: OBJECTIVE
  To compare the ingredients of essential oils of Curcuma wenyujin extracted by supercritical-CO2 fluid extraction and by steam distillation.
  
  
  METHODS
  GC-MS was applied in this experiment.
  
  
  RESULTS
  The ingredients and physical and chemical properties of essential oils of C. wenyujin extracted by supercritical-CO2 fluid extraction and by steam distillation are similar.
  
  
  CONCLUSIONS
  Supercritical-CO2 fluid extraction is better than steam distillation in extraction time, power consumption, recovery and purity.
