摘 要:建立了同位素标记-超高效液相色谱-串联质谱法测定畜肉、禽肉、鱼肉、牛奶和鸡蛋中普萘洛尔、美托洛尔、卡替洛尔、阿替洛尔4种β-阻断剂残留的检测方法。样品酶解后经乙腈提取,通过式固相萃取柱净化,超高效液相色谱-串联质谱仪测定,同位素内标法定量。结果表明,4种β-阻断剂在相应质量浓度范围内线性关系良好,相关系数均大于0.995,检出限为0.5μg·kg^(-1),方法回收率在78.4~102.6%之间,相对标准偏差(n=6)为1.9~8.7%。该方法简便快速,灵敏度高,实用性强,可用于动物源性食品中4种β-阻断剂残留检测。A method for the determination of propranolol、metoprolol,carteolol and atenolol inmeat、poultry fish,milk andeggswas established by isotope labeling-ultra-high performance liquid chromatography-tandem mass spectrometry.The sample was extracted with acetonitrile after enzymatic hydrolysis,and the extract was purified by pass-through solid phase extraction before being meas-ured by liquid chromatography-tandem mass spectrometry.The internal standard method was used for quantification.The results showed that good linear relationships were obtained for four ofβ-receptor blockers in the investigated concentration ranges with cor-relation coefficients more than 0.995.The limits of detection(LODs)were 0.5μg·kg^(-1).Average recoveries of the analytes in pork ranged from 78.4~102.6%,with relative standard deviations(RSDs)of 1.9~8.7%.The developed method was simple,rapid and practical,and could be used for the determination of fourβ-receptor blockers in animal originated food.
