Abstract: A gas chromatography(GC) method was developed for determination of indoxacarb residue in various food matrixes including green soybean,Brassica campestris L. grapefruit,ginger,agaric,bamboo shoot,tea,pork,fish and chicken. The indoxacarb residues in the samples were extracted with the mixture of acetone and n-hexane(1:2,V/V),and then the extracts were purified with ENVI-CARB solid phase extraction(SPE) cartridges for plant foodstuffs and Floirsil SPE cartridges for animal foodstuffs. For GC analysis,the limit of quantification(LOQ) is 0.005 mg/kg,and the average recoveries and relative standard deviation(RSD) for the spiked samples in the range of 0.005 to 0.04 mg/kg are in the range of 74.9% to 106.4% and 1.9% to 11.5%,respectively.
