摘要

该研究建立了应用固相萃取(solid-phase extraction, SPE)结合气相色谱-质谱联用法(gas chromatography-mass spectrometry, GC-MS)快速测定食醋中川芎嗪(tetramethylpyrazine, TMP)含量的分析方法。样品经Poly-Sery HLB Pro SPE小柱净化后,采用GC-MS外标法定量。该方法重复性及仪器精密度的相对标准偏差(relative standard deviation, RSD)均小于3%,加标回收率为96.90%~100.79%。TMP在0.1~100 mg/L质量浓度内线性关系良好,相关系数r2>0.999 9。方法的检出限为0.309 μg/L,定量限为1.031 μg/L。该方法定量准确、操作简便、灵敏度高,适用于食醋中TMP的测定。此外,对地理标志产品山西老陈醋和非地理标志陈醋样品分析,结果表明两类产品中TMP含量差异显著。

Abstract

This study established a rapid method for quantitative determination of tetramethylpyrazine (TMP) in vinegar by using solid-phase extraction (SPE) coupled with gas chromatography-mass spectrometry (GC-MS).The vinegar samples were purified by Poly-Sery HLB Pro SPE solid phase extraction column, and then quantified by external standard method with GC-MS.The method demonstrated good repeatability and instrument precision, with RSDs of less than 3%, and the recovery rates were 96.90%-100.79%.Excellent linearity for TMP was achieved over the concentration range of 0.1-100 mg/L, with the correlation coefficient (r2) of 0.999 9.In addition, the detection limit (LOD) was 0.309 μg/L and the quantification limit (LOQ) was 1.031 μg/L.This method was accurate, simple to operate, and highly sensitive, making it suitable for TMP determination in vinegar.Furthermore, an analysis of the tetramethylpyrazine (TMP) content in geographical indication (GI) Shanxi aged vinegar and non-GI vinegar samples was conducted.The results indicated a significant difference in the TMP content between the two product categories.
