摘要
建立了同时检测海产品中土霉素、四环素、金霉素、氯霉素残留的高效液相色谱分析方法,以醋酸铵-醋酸/水缓冲液和乙腈作为流动相,通过二元梯度洗脱,使四种抗生素获得了较好的分离,以基线噪音的3倍计算,土霉素、四环素、金霉素、氯霉素的最低检出浓度分别为32、15、23、19vg/kg,在添加浓度范围内,四种抗生素的加标回收率为76%~92%,相对标准偏差为0.8%~4.5%,该方法快速、灵敏、准确,可靠性高,可用于海产品中抗生素残留的色谱分析。
A method for simultaneous determination of oxytetracycline, tetracycline, chlortetracycline and choramphenicol in seafood was successfully developed using high performance liquid chromatography with ammonium acetate/water and acetonitrile as the mobile phase. The results showed that the four antibiotics were well separated under the optimum conditions, with the limits of detection being 32 μg/kg for oxytetracycline, 15 μg/ kg for tetracycline, 23 μg/kg for chlortetracycline, and 19 μg/kg for choramphenicol. The recovery of standard additions was 76 %- 92 % and the relative standard tire, accurate and reliable and can be applied in the deviation was 0.8 % - 4.5 %. The method is rapid, sensianalysis of antibiotic residues in seafood
