超高效液相色谱-串联质谱法检测动物源食品中8种氨基糖苷类药物残留

建立了动物源食品中大观霉素，链霉素，双氢链霉素，阿米卡星，卡那霉素，安普霉素，庆大霉素和新霉素等8种氨基糖苷类药物残留检测的超高效液相色谱 串联质谱（UPLC-MS/MS）方法。结果表明：8种氨基糖苷类药物在0.05～2 mg?L^-1浓度范围内呈现良好的线性关系，相关系数R²均大于0.998；方法检测限为5 μg?kg^-1，定量限为10 μg?kg^-1；从100、200和300 μg?kg^-1 3个添加浓度检测结果可以看出，方法平均回收率为83.0%～114.1％，批内RSD为1.1%～11.4％，批间RSD为2.1%～8.9％，可以满足食品安全有关法规的要求。

Determination of Aminoglycosides in Foodstuffs of Animal Origin by UPLC-MS/MS

Spectinomycin, streptomycin, dihydrostreptomycin, amikacin, kanamycin, apramycin, gentamicin and neomycin in foodstuffs of animal origin were detected by UPLC-MS/MS. The calibration curve is good linear between the peak areas and the concentrations of 0.05~2 mg?L^-1，the correlation coefficient R²＞0.998. The limit of detection is 5 μg?kg^-1, and the limit of quantification is 10 μg?kg^-1. The average recoveries from spiked milk at the three concentrations of 100, 200 and 300 μg?kg^-1 range from 83.0%～114.1％, and intra- and inter-batch variation coefficients are 1.1%～11.4％ and 2.1%～8.9％,respectively.
