摘要

采用Agilent公司的增强型脂质去除产品Bond Elut EMR-Lipid,建立了针对猪肉中四环素类药物残留的更快更高效的QuEChERS样品前处理方法。样品经酸化乙腈提取，Bond Elut EMR-Lipid QuEChERS净化后，采用HPLC-MS/MS检测，方法检出限可达5.0 μg/kg；四环素、金霉素和强力霉素的回收率为75.6%~89.4%，土霉素的回收率为53.4%~61.0%，相对标准偏差均不大于7.7%。

Abstract

A modified QuEChERS sample pretreatment method was established for the determination of tetracycline residues in pork.The new method adopted a novel lipid-removal material(EMR-Lipid) in QuEChERS procedure,and provided fast and effective sample extraction and cleanup of high-fat sample such as pork.The LODs of the method were 5.0 μg/kg.The recoveries of tetracycline,chlortetracycline,doxycycline were in the range of 75.6%-89.4% and the recoveries of oxytetracycline were in the range of 53.4%-61.0%,with RSDs not more than 7.7%.
