title: [Determination of organochlorine pesticide residues in Microcos paniculata by GC].
abstract: OBJECTIVE
  To establish a method for determination 9 organochlorine pesticide residue in Microcos paniculata by gas chromatography.
  
  
  METHODS
  The sample was infiltrated with water and extracted with hexane by ultrasonic. The extract solvent was purified by concentrated sulphuric acid. DB-1701 capillary column was used to separate the sample. GC-ECD was applied to determine the residues of organochlorine pesticide.
  
  
  RESULTS
  The percentage recoveries were ranged from 78.1% to 97.8% and RSD were from 2.4% to 8.8%.
  
  
  CONCLUSIONS
  The method established is quick, simple and low in cost.
