title: [Studies on chemical components of essential oil of crude semen sinapis and roasted semen sinapis].
abstract: OBJECTIVE
  To study the chemical components of the essential oil of the Semen Sinapis with the different processing methods.
  
  
  METHODS
  The essential oils of the crude Semen Sinapis and the roasted Semen Sinapis were extracted by steam distillation. The chemical components were analyzed by means of GC-MS-DS. The relative content of each component was calculated by area normalization.
  
  
  RESULTS
  The main chemical components of the essential oil of the crude Semen Sinapis and the roasted Semen Sinapis were similar. The main chemical components were allyl isothiocyanate and 4-isothio-cyanato-1-butene. The chemical components of the essential oil of the crude Semen Sinapis were more than that of the roasted Semen Sinapis.
  
  
  CONCLUSIONS
  The effect of different processing methods on the chemical components of the essential oil of Semen Sinapis was significant. Certain chemical components such as isothiocyanato-containing substances, were found in the crude Semen Sinapis.
