title: [GC-MS analysis of volatile aromatic substances in Chaenomeles speciosa fruit].
abstract: OBJECTIVE
  To analyze the volatile aromatic substances in Chaenomeles speciosa fruit produced in Chongqing in order to provide the characteristic data for it's resources development and flavors chemistry research.
  
  
  METHODS
  The volatile aromatic substances were extracted by steam distillation from Chaenomeles speciosa fresh fruit and seperated and identified by GC-MS.
  
  
  RESULTS
  106 volatile aromatic substances were seperated and identified, mainly including esters, alcohols, carboxylic acids, alkanes and alkenes, ketones, which made a great contribution to flavor of Chaenomeles speciosa fresh fruit.
  
  
  CONCLUSIONS
  This study elucidated the composition of volatile aromatic substances in Chaenomeles speciosa fruit produced in Chongqing, which could provide basic information for exploitation and utilization of it's flavor substances.
