摘要:

研究了一种针对水产品中残留孔雀石绿和无色孔雀石绿的液质联用分析方法。采用固相萃取方法对样品中的目标物进行净化前处理,以乙腈- 醋酸铵缓冲液作流动相分析食品中的孔雀石绿和无色孔雀石绿,缩短了色谱分离时间,提高了检测灵敏度和分析结果的可靠性,并对柱后衍生化和非衍生化方法以及DAD 和MS 检测方法进行了比较。结果表明本方法具有准确、快速以及灵敏度高的特点,能够适应大规模样品的快速分析要求,目前此方法已经用于水产品中残留孔雀石绿的分析检测。

Abstract:

In this study, solid phase extraction was used in pretreatment. After separated by HPLC with acetronitrile-ammonium acetate buffer as mobile phase, malachite green (MG) and leucomalachite green (LMG) in foods were detected by MSD in the ESI(+)-SIM mode. This analytical approach is highly sensitive, rapid and precise, therefore it has enormous application value.

Key words: malachite green, leucomalachite green, HPLC/MS, aquatic
