Abstract: A method for rapid determination of fifteen organochlorine and pyrethroid insecticide residues (included α-HCH,β-HCH,γ-HCH,δ-HCH,p,p'-DDE,o,p'-DDT,p,p'-DDD,p,p'-DDT,PCNB,aldrin, fenpropathrin, permethrin,cypermethrin,fenvalerate,deltamethrin) in two kinds of Chinese crude drugs (Raidix paeoniae Alba and Rhizoma coptidis) were developed.The sample was extracted in Soxhlet with petroleum ether (60~90°C) and cleaned up with the mixture of aluminum oxide-florisil (5 g and 7 g),detected by GC-ECD.The limit of detection (LOD) of 15 organochlorine and pyrethroid insecticides were 0.000 5~0.006 0 ng,and the limit of quantitation (LOQ) of the method for 15 organochlorine and pyrethroid insecticides in Raidix paeoniae Alba and Rhizoma coptidis were 0.005~0.050 mg/kg,and fortified recovery of pesticides at three levels were 79.8%~114.6%, the RSD were below 10% (n=6).
