摘要

建立了气相色谱-串联质谱（Gas chromatography-tandem mass spectrometry,GC-MS/MS）同时测定茶鲜叶中20种邻苯二甲酸酯类化合物的分析方法。茶鲜叶中的邻苯二甲酸酯类化合物经0.1%乙酸乙腈提取、氯化钠盐析、Florisil固相萃取柱净化、乙腈定容,色谱程序升温分离,多反应监测模式扫描（Multiple reaction monitoring,MRM）,外标法定量。通过优化样品提取、净化以及色谱条件,目标化合物在0.010~2.0 mg·kg^-1范围内线性良好,决定系数（R²）>0.995 5;在0.010、0.10 mg·kg^-1和1.0 mg·kg^-1 3个添加水平下,平均回收率在70%~118%,相对标准偏差（RSD）<17.8%;方法的定量限为0.010~0.10 mg·kg^-1。该方法稳定、可靠,可满足茶树鲜叶中邻苯二甲酸酯类化合物的检测需要。

Abstract

In this paper, an analytical method for the simultaneous determination of 20 phthalate esters in tea fresh leaves was developed by gas chromatography-tandem mass spectrometry (GC-MS/MS). The phthalate esters in tea fresh leaves were extracted by 0.1% acetonitrile acetate, salted out with sodium chloride, cleaned up with a florisil solid phase extraction column, resolved with acetonitrile, separated by temperature programmed chromatography, monitored with multiple reaction monitoring (MRM) mode, and quantified by the external standard method. Through the optimization of sample extraction, purification and chromatographic conditions, good linearity of the target compounds was obtained in the concentration range of 0.010-2.0 mg·kg^-1 with the corresponding coefficient of determination R²>0.995 5. The average recoveries ranged from 70% to 118% at the three spiked levels of 0.010 mg·kg^-1, 0.10 mg·kg^-1 and 1.0 mg·kg^-1, with the relative standard deviations (RSDs) of <17.8%. The limits of quantification were 0.010~0.050 mg·kg^-1. The method is stable and reliable, and it can meet the needs of the determination of phthalate acid esters in tea fresh leaves.

Key words： gas chromatography-tandem mass spectrometry; phthalate acid esters; tea fresh leaves
