title: [GC-MS analysis of chemical constituents of essential oil from Callicarpa kwangtungensis and their antimicrobial activity].
abstract: OBJECTIVE
  To analyze the chemical constituents of the essential oil from Callicarpa kwangtungensis and investigate their antimicrobial activity in vitro.
  
  
  METHODS
  The essential oil of Callicarpa kwangtungensis were extracted by steam distillaton. The chemical constituents were separated and analyzed by GC-MS. Their relative percentages were calculated with peak area normalization method.
  
  
  RESULTS
  38 compounds were identified, accounting for 76.01% of the peak area of the total ion-current chromatogram. The essential oil had different antimicrobial activities.
  
  
  CONCLUSIONS
  The main constituent of the essential oil is terpenoids (59.25%), and showing different activities against Staphylococcus aureus, Escherichia coli and Candida albicans.
