摘要: An analytical method was developed to detect the residue of mebendazole and its metabolites (hydroxymebendazole and aminomebendazole) in the muscle of grass carp and shrimp by LC-UV detection. Mebendazole and its metabolites were extracted with water and ethyl acetate, defatted with hexane, and purified with MCX solid phase extraction column. The intra- and inter-batch precision (measured by CV%) was <9.0%. The accuracy (measured by relative error, %) was <12%. The LODs were 2.5 μg kg~(-1) for mebendazole and hydroxymebendazole, 5 μg kg~(-1) for aminomebendazole; the LOQs were 5 μg kg~(-1) for mebendazole and hydroxymebendazole, 10 μg kg ~(-1) for aminomebendazole. The mean recoveries of mebendazole and its metabolites from grass carp and shrimp muscle at a concentration range of 5.0-500.0 μg kg~(-1) were 90.7-97.0% with relative standard deviations below 10%.
