摘要
本研究采用高效液相色谱法检测了磺胺二甲嘧啶在鸡蛋中的残留。产蛋鸡饲料添加药物磺胺二甲嘧啶,浓度分别为500mg/Kg、1000mg/Kg、2000mg/Kg,连喂3天,测定蛋中磺胺二甲嘧啶的药物残留。结果表明:喂药后,在停药第一天浓度积累到最高,残留浓度分别为5.669mg/Kg,17.219mg/Kg,50.388mg/Kg,分别占饲料中药物浓度1.134%,1.722%,2.519%,停药后,分别在第5天、第7天、第8天低于检测限度。
A high-performance liquid chromatographic method was reported for the quantitative detection of residues of SM 2 .the hens were fed successively SM 2 feeds of500mg /Kg ,1000mg /Kg and2000mg /kg for three days.on the first withdrawal day,the residues were the highest,the quan tity was5.669mg /Kg,17.219mg /Kg ,50.388mg /Kg repectively,the concentration of SM 2 excreted into eggs after oral dosage were1.134%,1.722%,2.519%of the concentration in diet respectively.residues of SM 2 in eggs were lower than20μg /Kg on the5th,the7th,the8th withdrawal day re spectively.
