摘要: 目的:建立快速溶剂提取动物组织中磺胺类抗生素残留的方法,并将该方法与超声波辅助提取法、匀浆法比较。方法:以样品添加回收率为指标,探索各种提取参数的影响,优化提取条件。结果:选出了加速溶剂提取法的最适条件:二氯甲烷为提取溶剂,提取压力500psi,温度40℃,整个提取过程需时23min,提取溶剂12ml,六种磺胺的添加回收率均高于80%,相对标准偏差在9%以下。结论:加速溶剂提取与超声波辅助提取法、匀浆相比,是一种快速、高效的提取方法。

Abstract: Objective: Accelerated solvent extraction (ASE) was applied to extract six sulfonamide residues in animal tissues, and compared with ultrasonic-assistant extraction or homogenization extraction. Methods: Various extracting parameters were investigated to optimize the extracting conditions that would affect the recovery of sulfonamides during ASE. Results: The suitable conditions of ASE are as follows: samples extracted with dichloromethane, operating pressure is 500 psi, temperature 40℃, extracting time 23 min and the collected volume 12 ml. Recovery of any sulfonamides is higher than 80% and the relative standard deviation (RSD) less than 9%. Conclusion: Comparing with traditional method, the ASE is rapid and effective.
