中文摘要	建立了一种适用于肉鸡毛发中诺氟沙星残留分析的方法。毛发样品经医用纱布包裹后清洗,剪碎后加入4 mol/L氨水超声提取,Oasis HLB修饰磁纳米材料用于净化提取液,采用Agilent Eclipse Plus C_(18)色谱柱分离,电喷雾正离子源进行离子化,多反应监测方式(MRM)对诺氟沙星的母离子及子离子进行监测,三重四极杆质谱测定。该方法鸡毛中诺氟沙星在1.0~100.0 mug/kg范围线性良好,相关系数为0.9928;诺氟沙星检出限为0.3 mug/kg,定量限为1.0 mug/kg,方法回收率为89.2 %~95.7%;相对标准偏差(RSDs)均小于10%。方法可满足政府和企业在肉鸡饲养期间对诺氟沙星的监控需求。
英文摘要	A method for the identification and quantification of norfloxacin residue in broiler hair samples by LC-MS/MS was developed.Hair samples were cleaned after being wrapped in gauze, then sheared and added to 4 mol/L ammonia solution for ultrasonic extraction.The extract was purified by Oasis HLB modified magnetic nanomaterials.The samples were analyzed by LC-MS/MS.The LC separation was performed on an Agilent Eclipse Plus C_(18) column.Multiple reaction monitoring(MRM) was used for the selective detection of norfloxacin.The good linearity curve of norfloxacin was in the range from 1.0 to 100.0 mug/kg with correlation coefficient of 0.9928.And the limit detection and limit of quantification were 0.5 and 1.0 mug/kg in spiked hair samples, respectively.The recoveries of norfloxacin were 89.2 %-95.7%, and the relative standard deviations(RSDs) were less than 10%.The established method could meet the need of government and enterprises to monitor the illegal use of norfloxacin during the whole rearing period.
