title: [Chemical and biological studies on essential oil from Ficus tsiangii].
abstract: OBJECTIVE
  To analyze the chemical components of the essential oil extracted from the bark of Ficus tsiangii.
  
  
  METHODS
  The essential oil was extracted by water-steam distillation and separated by GC capillary column chromatography. The components were quantitatively determined with normalization method and identified by GC-MS; Oxidation levels were used to study the antioxidation of the essential oil. Born turbidimetric method was applied to study the action of the the essential oil on rabbit platelet aggregation in vitro.
  
  
  RESULTS
  The oil rate of Ficus tsiangii was 0.097%. 198 chromatographic peaks were detected and 57 compounds were identified, which were composed of 72.06% of the total essential oil. The highest ingredients in essential oil were fatty acids. The essential oil had no antioxidation and a weak inhibitory effect of the ADP-induced platelet aggregation.
  
  
  CONCLUSIONS
  The chemical and biological data of the essential oil were reported for the first time.
