[Objective] The research aimed to determine the contents of organochlorine pesticides residues in soils from genuine producing areas of RHIZOMA COPTIDIS.[Method] Gas chromatographic method was employed to determine the contents of organochlorine pesticides residues in soil samples from genuine producing areas of RHIZOMA COPTIDIS by reference to GB/T 14550-2003 standard.[Results] The results showed that the contents of organochlorine pesticides residues in the soil samples satisfied the standard.[Conclusion] Soil samples from most of the genuine producing areas of RHIZOMA COPTIDIS conformed to the GAP plantation requirement of traditional Chinese medicinal materials,which provided a foundation for guaranteeing the high-quality and security of RHIZOMA COPTIDIS medicinal materials.
