A novel precolumn derivatization-GC-MS/MS method was developed for the determination of decoquinate residues in chicken tissues (muscle, liver, and kidney). The samples were extracted and purified by liquid-liquid extraction combined with solid-phase extraction and derivatized with acetic anhydride and pyridine. The recovery rates for decoquinate were 77.3889.65%, and the intra-day and inter-day RSDs were 1.635.74% and 2.27~8.06%, respectively. The technique parameters meet the necessities for veterinary drug residue detection in China, the US, and the EU. Finally, the method was applied to analyze tissues of 60 chickens bought from a neighborhood supermarket, and solely one sample of chicken muscle contained 15.6 μg/kg decoquinate residue.
建立了一种新的柱前衍生化-气相色谱-串联质谱法，用于测定鸡组织（肌肉、肝脏和肾脏）中的癸氧喹酯残留。样品经液-液萃取结合固相萃取提取和净化，然后用乙酸酐和吡啶衍生化。癸氧喹酯的回收率为 77.38%89.65%，日内和日间相对标准偏差分别为 1.63%5.74%和 2.27%~8.06%。该技术参数符合中国、美国和欧盟兽药残留检测的要求。最后，该方法应用于分析从附近超市购买的 60 只鸡的组织，仅在一份鸡肌肉样品中检测到 15.6μg/kg 的癸氧喹酯残留。
