title: [Analysis on the volatile oil in Origanum vulgare].
abstract: OBJECTIVE
  To analysis compositions of the volatile oil in Origanum vulgare.
  
  
  METHODS
  GC-MS condition: using programmed temperature gas chromatography cinitial temperature was 60 degrees C, and then raising the temperature (5 degrees C/min) to 240 degrees C, mass-to-electric charge ratio was 10 to 425.
  
  
  RESULTS
  GC-MS identified 29 kinds of contents.
  
  
  CONCLUSIONS
  Thymol and carvacrol are main compositions of the volatile oil in Origanum vulgare.
