title: [Analysis of volatile oil from Ardisia brevicaulis].
abstract: OBJECTIVE
  To analyze and compare the compounds in the essential oil from the leaves and roots of Ardisia brevicaulis.
  
  
  METHODS
  The essential oil were obtained by steam distillation. The chemical components were separated and identified by gas chromatography-mass spectrometry (GC-MS).
  
  
  RESULTS
  38 compounds were identified from the leaves (65.952% of the total essential oil) and 46 compounds were identified from the roots (54.890% of the total essential oil). The main constituents of the leaves essential oil were Palmitic acid (43.329%), Fitone (2.430%), Phytol (3.142%), and so on. The main constituents of the roots essential oil were Calamenene (2.913%), cis-alpha-Bisabolene (5.222%), gamma-Muurolene (14.227%), Caryophyllene (11.592%), and so on.
  
  
  CONCLUSIONS
  The constituents of volatile oil extracted from the leaves and roots of Ardisia brevicaulis were different, so the leaves and roots of Ardisia brevicaulis should be utilized differently in clinical application.
