摘要:

为建立鱼肌肉中16种麻醉剂残留的同步检测方法,本研究以磁性纳米材料为净化吸附剂,基于QuEChERS前处理技术,结合液相色谱-串联质谱(LC-MS/MS)建立了鱼肌肉中卡因类、苯二氮卓类和吩噻嗪类麻醉剂的检测方法。优化了萃取溶剂类型、磁性纳米材料Fe3O4@SiO2@DVB-NVP(聚二乙烯基苯-吡咯烷酮,Fe3O4-PLS)和N-丙基乙二胺(PSA)用量对目标物回收率的影响。确定以含0.5%(体积分数)乙酸的乙腈为萃取剂,氯化钠(NaCl)和无水硫酸镁(MgSO4)为盐析与除水材料,20 mg Fe3O4-PLS、10 mg PSA为净化吸附材料。在正离子电喷雾模式下,采用Luna Omega C18色谱柱(100 mm×2.1 mm,1.6 μm)分离,外标法定量。 结果表明,16种麻醉剂在0.5~200 μg·kg-1范围内线性关系良好,相关系数(r)≥ 0.996,仪器检出限(limit of detection, LOD)为0.08~0.57 μg·L-1。在1、10、100 μg·kg-1的添加水平下,16种麻醉剂的平均加标回收率为72.4%~110.8%,日内相对标准偏差(relative standard deviation, RSD)为0.4%~7.7%。实际样品分析中,三卡因和苯佐卡因检出率分别为26.1%和39.1%,二者的检出质量分数范围分别为2.07~6.34 μg·kg-1和1.44~2.87 μg·kg-1。本方法实用性强,可为鱼肌肉中16种麻醉剂的高通量残留分析提供参考。

Abstract:

To establish a simultaneous determination method for 16 anesthetic residues in fish muscle, a detection method for caine-type, benzodiazepines, and phenothiazine anesthetics in fish muscle was developed based on a QuEChERS pretreatment technique using magnetic nanomaterials as clean-up adsorbents, combined with liquid chromatography-tandem mass spectrometry (LC-MS/MS). The effects of extraction solvent type, the dosage of magnetic nanomaterial Fe3O4@SiO2@DVB-NVP(polyvinylphenylpyrrolidone, Fe3O4-PLS) and N-propylethylenediamine(PSA) on the recovery rate of the target substance were optimized. It was determined that 0.5%(volume fraction) acetic acid in acetonitrile was used as the extractant, sodium chloride (NaCl) and anhydrous magnesium sulfate (MgSO4) were used as the salting out and water removal materials, and 20 mg Fe3O4-PLS and 10 mg PSA were used as the purification and adsorption materials. In the positive ion electrospray mode, the Luna Omega C18 chromatographic column(100 mm×2.1 mm, 1.6 μm) was used for separation and quantification by the external standard method. The results showed that the 16 anesthetics had good linearity within the range of 0.5 to 200 μg·kg-1, with correlation coefficient(r) ≥ 0.996, and the limit of detection(LOD) of the instrument was 0.08-0.57 μg·L-1. At the addition levels of 1, 10, and 100 μg·kg-1, the average spiked recovery rates of the 16 anesthetics ranged from 72.4% to 110.8%, with intra-day relative standard deviation (RSD) of 0.4%-7.7%. In the analysis of real samples, the detection rates for tricaine and benzocaine were 26.1% and 39.1%, respectively, with detected mass fraction ranges of 2.07-6.34 μg·kg-1 and 1.44-2.87 μg·kg-1, respectively. This method has good practicability and can provide reference for the high-throughput residue analysis of the 16 kinds of anesthetics in fish muscle.
