Methods The residues of amantadine in the test samples were extracted with methanol-1% trichloroacetic acid (1:1, v/v). After being cleaned up with SPE column, the analytes were detected by LC-MS/MS under multiple reaction monitoring (MRM) via positive ionisation mode. Results The limit of quantification was 5.0 μg/kg. The method showed a good linearity over the range of 1~100 μg/kg for amantadine with r> The average recoveries at 3 spiked concentration levels were between 89.0%~98.7%, while the relative standard deviations (RSD) were between 0.3%~2.5% (n=5) and bias were between 1.9%~5.5% (n=5). Conclusion The established method is highly sensitive, accurate and reproducible. It is suitable for the detection of amantadine in chicken.
