摘要

建立了水产品中11种海洋生物毒素的高效液相色谱-四极杆/静电场轨道阱高分辨质谱(HPLC-Q-Orbitrap HRMS)检测方法。该方法采用分级提取原理，结合分散固相萃取技术(dSPE)和载体辅助液液萃取技术(SLLE)，建立了对亲水性及亲脂性海洋生物毒素的“一站式”提取净化体系。在优化条件下，11种毒素在一定质量浓度范围内具有良好的线性关系，相关系数(r)均大于0.99。该方法对11种毒素的检出限为1~10 μg/kg，定量下限为2~20 μg/kg，加标回收率为55.6%~122%，相对标准偏差为5.4%~16%。方法快速高效，可操作性强，解决了不同理化性质的海洋生物毒素的通用性检测问题，可满足水产品中海洋生物毒素的快速筛查要求。

Abstract

A method was established for the determination of 11 marine biotoxins in seafood by high performance liquid chromatography-quadrupole electrostatic field orbitrap high resolution mass spectrometry(HPLC-Q-Orbitrap HRMS).It was a one stop extraction and purification system for hydrophilic and lipophilic marine biotoxins.Samples were firstly treated by sequential extraction procedure

then cleaned up by disperse solid phase extraction(dSPE) combined with carrier assisted liquid-liquid extraction(SLLE).Under the optimal conditions

the calibration curves for 11 marine biotoxins were linear in the certain concentration ranges

with correlation coefficients greater than 0.99.The limits of detection(LOD) and limits of quantitation(LOQ) were in the ranges of 1-10 μg/kg and 2-20 μg/kg

respectively.The spiked recoveries ranged from 55.6% to 122% with relative standard deviations(RSD) of 5.4%-16%.The method was simple

efficient and operable

and could solve the problem of high throughput detection of hydrophilic and lipophilic marine biotoxins in seafood and meet the requirements for rapid screening.
