| 摘 要： | 建立气相色谱-串联质谱测定动植物源食品中氯苯胺灵残留量的分析方法。样品采用优化QuEChERS及固相萃取法前处理，HP-5MS气相色谱柱进行分离，采用外标法进行定量。结果显示，本方法测定的香蕉样品在0.01～0.5 μg/mL范围内线性关系良好，测定的动物食品样品在0.03～1 μg/mL范围内线性关系良好，相关系数R2均大于0.999。在3 种基质中进行的加标回收实验测得回收率在80.6%～107.8%之间，相对标准偏差在2.3%～8.5%之间。本研究开发了动植物源食品中氯苯胺灵的检测方法，操作简便、重复性好，适用于批量样品检测，为评估氯苯胺灵的膳食摄入风险提供了理论依据。

| Abstract: | In this study, an analytical method for the determination of chlorpheniramine residues in foods of animal and plant origin by gas chromatography-tandem mass spectrometry (GC-MS/MS) was developed. The samples were pretreated with a modified quick, easy, cheap, effective, rugged, safe (QuEChERS) method and solid phase extraction, and the analytes were separated on HP-5MS GC column and quantitatively determined by an external standard method. The experimental results showed that the method exhibited a good linear relationship in the range of 0.01–0.5 and 0.03–1 μg/mL with correlation coefficient R2 higher than 0.999 for banana and an animal food sample, respectively. The spiked recoveries for three matrixes were measured to be 80.6%–107.8%, with relative standard deviation (RSD) of 2.3%–8.5%. This method was characterized by simple operation and good reproducibility. It was suitable for batch sample detection, providing a technical basis for evaluating the risk of dietary exposure to chlorpheniramine. |
