摘要:

为评估香烟烟气中杂环胺的暴露水平, 建立了一种基于低共熔溶剂/无机盐双水相萃取-UPLC法测定吸烟者尿液中5种杂环胺(IQ, IQ[4,5-b], Harman, Norharman和Phe-P-1)的方法. 制备了7种以氯化胆碱(ChCl)为氢键受体的低共熔溶剂, 并对其进行了表征; 系统考察了影响萃取效率的主要参数, 并将该方法与其它方法进行了对比研究. 结果表明, 在最佳提取条件下, 杂环胺(HAAs)的回收率为81.9%~106.2%, 日内和日间精密度分别低于2.9%和3.2%, 检出限和定量限分别为0.020~0.097 ng/g和0.19~0.39 ng/g. 该方法具有操作简单、 环境友好及单样品成本低等特点, 为尿液中杂环胺的检测提供了一种新方法, 在生物样品检测领域具有良好的开发与应用价值.

Abstract:

To assess the exposure to heterocyclic aromatic amines(HAAs) from tobacco smoke, a novel method, an aqueous two-phase system based on deep eutectic solvent(DES-APTS) followed by UPLC, was described to analyze five HAAs(IQ, IQ[4,5-b], Harman, Norharman, Phe-P-1) from the urine samples of smokers. Seven kinds of choline chloride(ChCl)-based DESs had been synthesized and characterized by 1H NMR and FTIR spectra. The significant parameters affecting the extraction efficiency of HAAs in the DES-ATPS procedure were systematically investigated. Under optimal extraction conditions, the recoveries for the target HAAs ranged from 81.9% to 106.2%. The obtained intra- and inter-day relative standard deviations(RSDs) were less than 2.9% and 3.2%, respectively. The detection limits(LODs) and quantification limits(LOQs) were obtained in ranges of 0.020—0.097 ng/g and 0.19—0.39 ng/g, respectively. The developed method of DES-ATPS, with its simplicity, good environment-friendliness and low-cost per sample, could be a promising alternative technique for rapidly extracting and quantifying HAAs from urine samples, and displayed great development potential in the field of the detection in biological samples.
