摘要: 建立鸡肉和鸡蛋中阿比多尔、金刚烷胺、金刚乙胺、美金刚、奥司他韦的在线固相萃取-液相色谱-串联质谱检测方法。样品采用1.0%甲酸-乙腈提取,经MCX在线固相萃取小柱净化,用XBridge C18色谱柱分离,使用电喷雾离子源正离子模式监测,以内标法定量。结果表明:5 种抗病毒类药物在0.05~100 ng/mL范围内线性关系良好;检出限为0.05~0.10 μg/kg,定量限为0.10~0.20 μg/kg;方法回收率范围为80.03%~93.96%,相对标准偏差低于10%。该方法分析速度快、灵敏度高,可用于鸡肉和鸡蛋中5 种抗病毒类药物的定性、定量分析。

Abstract: In this research, we developed an on-line solid phase extraction (SPE) combined with liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) method for the detection of arbidol, amantadine, rimantadine, memantine and oseltamivir in chicken meat and eggs. Samples were extracted with 1.0% formic acid in acetonitrile, and the extract was purified using an MCX on-line solid phase extraction cartridge. The target substances were separated using an XBridge C18 column, detected by electrospray ionization in the positive ion mode, and quantitated by the internal standard method. The results showed that the calibration curves of all analytes had a good linear relationship in the concentration range of 0.05–100 ng/mL. The limit of detection (LOD) and the limit of quantitation (LOQ) were 0.05–0.10 μg/kg and 0.10–0.20 μg/kg, respectively. The recoveries of the developed method were in the range of 80.03%–93.96%, with relative standard deviations (RSDs) of lower than 10%. The method was proven to be simple and sensitive, and could be used for the qualification and quantification of the five antiviral drugs in chicken meat and eggs.
