title: [Determination of chemical constituents of essential oil from the fruit of Eucalyptus globulus by GC-MS].
abstract: OBJECTIVE
  The chemical components of essential oil from fruit of Eucalyptus globulus were analyzed by GC-MS.
  
  
  METHODS
  The essential oil were extracted by steam distillation, then separated by capillary gas chromatography. The amount of the component from essential oil were determined by normalization methods. Chromatographic conditions were: capillary column DB-WAX (0.32 mm x 30 m, 0.25 microm) was used, column temperature: initial temperature at 40 degrees C for 3 min,ramping 5 C x min(-1) to 250 degrees C (holding for 10 min) the detector MS.
  
  
  RESULTS
  31 component from the fruit of E. globulus were identified, which accounted for over 93.7% of total volatile oil.
  
  
  CONCLUSIONS
  The methods is reliable, stabilize and can be applied to identify the volatile oil from the fruit of E. globulus.
