Abstract: An ultra performance liquid chromatography (UPLC)-tandem mass spectrometry analysis method was established in this experiment for determination of amantadine in chicken.1% trichloroacetic acid with methanol as extraction liquid, the ultrasonic assisted solvent extraction was used to extract amantadine in chicken, extract liquid was purified and enriched in MCX solid-phase extraction column.Using C18 chromatographic column as separation column, in the positive ion mode, we detected the samples by electrospray ionization tandem mass spectrometry.Mass spectrometry and chromatographic conditions, the type of extract liquid, ultrasonic extraction time, the types of solid-phase extraction column and eluent were optimized.Under optimal conditions, a good linearity (r=0.9998) in the ranges of 0.1 to 20.0 ng/mL was obtained, the recoveries were 89.7% to 101.4% in the additive levels of 5.0, 10.0 and 20.0 μg/kg, the limit of detection (LOD) of amantadine was 0.07 μg/kg, the limit of quantiation (LOQ) of amantadine was 0.23 μg/kg, and the relative standard deviations (RSD) were below 7.0%.This novel approach had high sensitivity and accuracy, and was successfully applied to rapid and high sensitive detection of amantadine residues in chicken.The positive samples of amantadine in chicken were successfully prepared with concentrations of 11.16 and 7.18 mg/kg, which could be used for the research of ELISA kits of amantadine.
