摘要
建立了高效液相色谱-串联质谱(HPLC-MS/MS)同时测定鲜湿米粉中乳酸链球菌素A(Nisin A)和乳酸链球菌素Z(Nisin Z)的分析方法。样品经p H 3.0的水(甲酸调节p H值)提取,以Hilic Plus色谱柱分离待测物,在电喷雾正离子化模式下,采用多反应监测(MRM)模式检测。结果表明,Nisin A和Nisin Z在100~2 000μg/L范围内线性关系良好,相关系数均大于0.999,方法检出限分别为0.01、0.02 mg/kg,回收率为95.6%~107.0%,RSD均小于2.0%。该方法准确、可靠,适用于鲜湿米粉中Nisin A和Nisin Z的含量检测。
A high performance liquid chromatography-tandem mass spectrometric(HPLC-MS/MS)method was developed for the simultaneous analysis of Nisin A and Nisin Z in fresh wet rice noodles.An extraction solution of formic acid(p H 3. 0) was used to extract Nisin A and Nisin Z in fresh wet rice noodles samples. The extract was separated on a Hilic column,and determined with electrospray ionization(ESI) source in positive ion mode under multiple reaction monitoring(MRM) mode. There were good linear relationships for the analytes between their peak area responses and concentrations of100-2 000 μg/L,with correlative coefficients larger than 0. 999. The limits of detection for Nisin A and Nisin Z were 0. 01 mg/kg and 0. 02 mg/kg,respectively. The recoveries were in the range of95. 6%-107. 0% with RSDs less than 2. 0%. The method was reliable and accurate,and was suitable for the determination of Nisin A and Nisin Z in fresh wet rice noodles.
