摘要:

目的:研究建立反相液相色谱法监控肉鸡组织阿奇霉素的残留。方法:采用C18 柱(4.6mm × 250mm,5μm),乙腈- 异丙醇-0.002mol/L 磷酸氢二钠(60:15:25,V/V)为流动相,紫外检测波长210nm,样品用氯仿- 异丙醇(95:5,V/V)提取,氮气流吹干,加流动相溶解后进样。结果:阿奇霉素在0.05~5.0μg/g 范围内与峰面积呈线性相关,r > 0.990;血清中最低检测限为0.02μg/ml,组织最低定量限为0.05μg/g,血清回收率> 83%,组织回收率> 77%,RSD < 5%。结论:该方法快速、精确、重复性好,符合肉鸡组织中阿奇霉素残留检测的要求。

Abstract:

Objective: A highly sensitive and specific method for determination of azithromycin residues in chicken tissues by reverse-phase high-liquid chromatography was developed. Methods: Based on separation on a C18 column (4.6 mm×250 mm, 5 μm) at 210 nm with the mobile phase of acetonitrile-lsopropylalcohol-0.002 mol/L phosphate (60:15:25, V/V), samples were extracted by using chloroform-lsopropylalcohol (95:5, V/V), dried by nitrogen flow, and injected after dissolution in the mobile phase. Results: A good linear relationship was obtained in the concentration range of 0.05 to 5.0 μg/g (r>0.990). The limit of detection in serum was 0.02 μg/ml and the limit of quantification in tissue was 0.05 μg/g. The average recoveries were over 83% in serum and over 77% in tissues, respectively, and both the intra-day and inter-day relative standard deviations were less than 5%. Conclusion: The method is quick and accurate, has good repeatability, and accords with the requirement for determining residues of azithromycin in chicken tissues.
