摘  要：
[目的]建立一种准确、快速测定动物源性食品中四唑虫酰胺残留量的分析方法.[方法]样品经乙腈提取,氯化钠和无水硫酸镁盐析分层,上层经m-PFC净化,高效液相色谱质谱联用仪测定,外标法定量.[结果]四唑虫酰胺在0.001~0.150 mg/L范围内线性良好,相关系数均>0.999,定量限为0.002 mg/kg;以猪肉、牛肉、羊肉、鸡肉、猪肝、牛肝、羊肝、鸡肝、鸡蛋、牛奶阴性样品为基质,四唑虫酰胺的平均加标回收率为 90.0%~108.0%,相对标准偏差为 1.10%~4.89%.[结论]该方法适用于动物源性食品中四唑虫酰胺的定量分析.

摘  要：
[Objective]This study aimed to develop a rapid and efficient method for quantifying tetraniliprole residues in animal-derived foods by combining multi-plug filtration cleanup(m-PFC)with high-performance liquid chromatography-mass spectrometry(HPLC-MS).[Methods]Samples were extracted with acetonitrile,followed by salting out using sodium chloride and anhydrous magnesium sulfate.The extracts were purified via m-PFC and analyzed using HPLC-MS with external standard calibration.[Results]The method demonstrated a strong linear correlation between tetraniliprole concentration and response values over a range of 0.001 to 0.150 mg/L,with a coefficient of determination(R2)exceeding 0.999.The limit of quantification(LOQ)was 0.002 mg/kg.Average recovery rates ranged from 90.0%to 108.0%,with relative standard deviations between 1.10%and 4.89%,validated across a variety of matrices,including pork,beef,mutton,chicken,pork liver,beef liver,mutton liver,chicken liver,eggs and milk.[Conclusion]The proposed method is rapid,straightforward,high sensitivity,and suitable for quantitative determination of tetraniliprole residues in animal-derived food.
