建立了猪肉中阿维菌素、伊维菌素、多拉菌素、莫两菌素,乙酰氨基阿维菌素等5种阿维菌素类药物以及地克珠利、妥曲珠利、妥曲珠利砜、妥曲珠利亚砜等4种均三嗪类药物及其代谢物残留的高效液相色谱.串联质谱分析方法.样品采用乙腈提取,ODS粉分散固相萃取净化,经Venusil ASB C18色谱柱(150 mm × 2.1 mm,3.0 p,m)分离,电喷雾串联四极杆质谱多反应离子监测方式测定.9种分析物在0.005~0.2 mg/L范围内线性关系良好,相关系数均大于0.990.猪肉基质中9种分析物在0.005、0.01、0.02 mg/kg加标水平下.回收率为73.2%~91.5%,相对标准偏差为12%~17%.该方法稳定、可靠,可满足猪肉中阿维菌素类、均三嗪类药物残留的检测与确证.
