title: [Study on the essential oil components in Thymus quinquecostatus Celak].
abstract: OBJECTIVE
  To analyse the essential oil components of Thymus quinquecostatus Celak.
  
  
  METHODS
  Gas chromatography/mass spectrometry were used.
  
  
  RESULTS
  A total of 78 components were separated. 34 of them were identified, which accounted for 95.93% of the total peak area. The main constituents are o-cymene, carvacrol, caryophyllene, 2-isopropyl-1-methoxy-4-methylbenzene and gamma-terpene.
  
  
  CONCLUSIONS
  Thymus quinquecostatus Celak has perfume and medical development value.
