[Determination of organochlorine pesticides redidues in traditional Chinese medicine including ginseng or American ginseng].
OBJECTIVE
To determine the residues of 19 organochlorine pesticides in traditional chinese medicine (TCM) including Radix ginseng or Radix panacis quinquefolii by capillary gas chromatograrhy.


METHODS
The samples were extracted with ethyl acetate by ultrasonic, then cleaned up by a column packed with Florisil. The capillary column was DB-1701 (30 m x 0.32 m, 0.25 microm). The electron capture detector (ECD) was used. The pesticide residues were calculated by external standard method.


RESULTS
The average recoveries and RSD ranged from 70.4% to 125.0% and 3.16% to 9.86%.


CONCLUSIONS
The method is rapid, simple and accurate. It can be used to determine organochlorine pesticide residues in TCM.
