摘要: 目的 建立稳定同位素内标超高效液相色谱-串联质谱联用法(ultra performance liquid chromatography-tandem mass spectrometry,UPLC-MS/MS)检测葡萄酒中16种真菌毒素的分析方法。方法 葡萄酒样品经乙腈提取后盐析,上清液用纯水1 ∶ 1稀释后过0.22 μm聚四氟乙烯针式滤膜,加入稳定同位素内标降低基质效应。采用ACQUITY UPLCBETH C18色谱柱(100 mm×2.1 mm,1.7 μm)分离,多反应监测模式(multiple reaction monitoring,MRM)下电喷雾离子源正、负离子模式,内标法定量。结果 16种真菌毒素在一定浓度范围内具有良好的线性关系,相关系数(r)均>0.999,方法检出限(limit of detection,LOD)在0.1~50.0 μg/kg之间,方法定量限(limit of quantification,LOQ)为0.3~165.0 μg/kg。在3个浓度的加标水平下,平均回收率为在62.7%~117.5%之间,相对标准偏差为2.0%~9.5%(n=6)。结论 该方法操作简单、高效、成本低,具有较好的准确度和精密度,可用于大批量葡萄酒中16种真菌毒素的快速、准确定量检测。

Abstract: Objective To establish a method for the simultaneous determination of 16 kinds of mycotoxins in wine by isotope dilution-ultra performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS). Methods The wine samples were extracted by acetonitrile,the extract was salted out and dehydration. The supernatant diluted with water 1 ∶ 1 and then filtrated with 0.22 μm polytetrafluoroethylene millipore filter,the matrix effects were efficiently reduced with the stable isotope. The target substances were separated on ACQUITY UPLCBETH C18(100 mm×2.1 mm,1.7 μm). The multiple reaction monitoring(MRM) mode was used for detection in electrospray ionization with positive and negative ion modes,and quantified by internal standard method. Results There was a good linearity for 16 kinds of mycotoxins within a certain concentration range,the correlation coefficients(r) were greater than 0.999,the limits of detection(LOD) and limit of quantification(LOQ) were 0.1-50.0 μg/kg and 0.3-165.0 μg/kg,respetively. The average recoveries were 62.7%-117.5% at three different levels,and the relative standard deviations were 2.0%-9.5%(n=6). Conclusion The method is simple,efficient,low-consumption,and has good accuracy and precision,which is uitable for the rapid and accurate quantitative detection of 16 mycotoxins in large quantities of wine.
