摘要
为了快速准确的检验水产品四环素类(四环素、土霉素、金霉素)抗生素的残留,本论文建立水产品中四环素类抗生素残留的提取、净化和色谱测定的液质联用法。实验结果表明四环素类标准品的3个添加浓度(20、50、100)μg/kg的平均回收率范围为84%～112%,相对标准偏差小于18.4%,四环素类药物的检测限均可达到20μg/kg。液质联用法灵敏度高、准确可靠,前处理快捷简便,能够降低检测成本,可作为大量批次水产品中四环素类抗生素残留检测的常用方法。
In order to fast and accurate test of five tetracycline antibiotics （TCs） residues in aquatic food product {Tetracycline （TC）, Oxytetracycline （OTC）, and Chlortetracyline （CTC）}, a high performance liquid-MS/MS detection method was developed. Results showed that the average recoveries of the Tetracycline at the three concentrations of （20, 50 and 100） ug/kg were from 84% to 112% with relative standard deviation less than 18.3%. The detection limits of the TCs were 20ug/kg. For its high sensitivity, stability, the fast and easy pre-treatment and the reducing test costs, this method can be used for determination of tetracycline antibiotics residues in aquatic products.
