摘  要:
本研究探讨了用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)残留的方法,确定了从鸡蛋中提取、净化微量磺胺药物的条件。鸡蛋经二氯甲烷提取,用固相萃取柱净化处理后上机检测。结果显示,7种磺胺药物标准曲线的相关系数(r)为0.999 5~0.999 9,在0.05~0.20 mg/kg浓度范围内,回收率达73.2%~102.6%,变异系数为1.8%~8.7%,检测限为0.01~0.03 mg/kg。本方法准确度高,效果稳定,耗时少,为监控鸡蛋品质和评定无公害鸡蛋提供了有效的检测手段。

摘  要:
A high-performance liquid chromatography method for the multi-residues determination of sulfadiazine,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 C-18 column solid-phase extraction(SPE).The calibration curves for seven sulfonamides were linear in a concentration range of 0.05—(0.20 mg/kg)(r=0.999 5—0.999 9).The recoveries at levels of 0.05,0.10,(0.20 mg/kg) fortified samples ranged from 73.2%—102.6%,with coefficient of variation of 1.8%—8.7%.The limits of detection were 0.01—(0.03 mg/kg).It is a high-accurate,stable and less time-consuming method,which provide a valid analytical method for eggs quality control and assessment.
