摘要:

建立腊肠中罗丹明B(rhodamine B)残留量的高效液相色谱串联质谱检测方法。试样中残留的罗丹明B 用乙酸乙酯- 环己烷(1:1,V/V)提取,经凝胶色谱净化系统净化并浓缩后,用液相色谱- 质谱/ 质谱仪测定,外标峰面积法定量。罗丹明B 在5~100ng/mL 范围内呈良好的线性关系,3 个水平(5.0、10.0、25.0μg/kg)添加罗丹明B 的回收率为79.8%~110.3%,相对标准偏差(RSD)为10.0%~10.3%,检出限为5μg/kg。本方法简单、快速,适用于腊制品中残留罗丹明B 的检测。

Abstract:

A high-performance liquid chromatography-tandem mass spectrometric (HPLC-MS/MS) method was developed for the determination of rhodamine B residue in Chinese preserved sausages. The whole determination procedure consisted of extraction with a mixture of ethyl acetate and cyclohexane (1:1, V/V), cleanup with an Accuprep gel filtration chromatographic system, rotary evaporation concentration, filtration through 0.22 μm membrane, HPLC-MS/MS analysis, and quantitation by external standard method. The developed method showed a good linearity over the wide range of 5-100 ng/mL. Average recoveries of rhodamine B in spiked samples at three levels varied from 79.8% to 110.3%, with relative standard deviations between 10.0% and 10.3%. The limit of detection was 5 μg/kg. Therefore, this method, thanks to its simplicity and rapidity, has a good applicability to the determination of rhodamine B residue in Chinese preserved sausages.

Key words: sausage, rhodamine B, high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS)
