摘要: 本试验研究建立了高效液相色谱法测定鸡蛋中7种磺胺药物(磺胺嘧啶、磺胺二甲基嘧啶、磺胺甲氧哒嗪、磺胺间甲氧嘧啶、磺胺甲恶唑、磺胺间二甲氧嘧啶和磺胺喹恶啉)残留的提取、净化和高效液相色谱分析条件,鸡蛋经二氯甲烷提取、固相萃取、净化处理后上机检测,7种磺胺药物标准曲线的相关系数(R2)为0.9995~0.9999,在0.05~0.2mg/kg浓度范围内,回收率为73.2%~102.6%,变异系数为1.8%~8.7%。检测限为0.01~0.02mg/kg,定量限低于0.05mg/kg。

Abstract: Ah igh-performancel iquidc hromatographym ethodf or them ulti-residuess imultaneous determinationo fs ulfadiazine, sulfamethazine, sulfamethoxypyridazine, sulfamonomethoxine, sulfamethoxazole, sulfadimethoxine and sulfaquinoxaline in eggs was described in this paper. The egg samples were extracted with dichloromethane, and cleaned upon by a C18 column solid- phase extraction (SPE). The calibration curves for seven sulfonamides were linear in a concentration range of 0.02~1.0μg/ml (R2=0.9995~0.9999).The recoveries at levels of 0.05,0.1,0.2mg/kg fortified samples ranged from 73.2%~102.6%, with coefficient of variation of 1.8%~8.7%. The limits of detection were 0.02mg/kg and the limits of quantification less than 0.05mg/kg.
