摘要: 为了优化现有液相色谱、液质联用伏马毒素检测方法中前处理的烦琐,并降低费用,建立一种轻简化液质联用法,用于检测玉米中的伏马毒素B1、B2和B3。首先用乙腈-水-甲酸溶液(50∶49∶1)提取玉米中的伏马毒素,再通过超高效液相色谱进行预分离[C18反相色谱柱,100 mm×2.1 mm,1.9 μm;流动相A:CH3OH-H2O(98∶2)+5 mmol/L CH3COONH4+1% HCOOH和流动相B:CH3OH-H2O(2∶98)+5 mmol/LCH3COONH4+1% HCOOH],最后用高分辨质谱进行定量检测。结果显示,建立的检测方法对1~1 000 μg/L 的伏马毒素B1、B2 和B3 具有良好的线性关系,相关系数r> 0.999;检出限(LOD)和定量限(LOQ)分别为0.16~0.31 μg/kg 和0.52~1.01 μg/kg;在3 个不同添加水平下,平均回收率为77.72%~102.79%,相对标准偏差(RSD)为1.07%~8.92%。综上,建立的轻简化液质联用法具有操作简单、稳定可靠、检测成本低的优点,可用于玉米中3种伏马毒素的检测。

Abstract: In order to optimize the complicated pre⁃processing of the existing liquid chromatography and liquid⁃mass methods,a simplified liquid⁃mass coupling method was established for the simultaneous determination of fumonisins B1,B2,B3 in corn.First,the corn samples were extracted with acetonitrile⁃water⁃formicacid solution(50∶ 49∶ 1).Then fumonisins were pre⁃separated by ultra performance liquid chromatography[C18 column,100 mm×2. 1 mm,1. 9 μm;Mobile phase A:CH3OH⁃H2O(98∶2)+5 mmol/L CH3COONH4+1% HCOOH;Mobile phase B:CH3OH⁃H2O(2∶98)+5 mmol/L CH3COONH4+1% HCOOH].Finally,quantitative detection was performed by high resolution mass spectrometry.The results showed that the method had a good linear relationship in the concentrationrange of 1—1 000 μg/L with the correlation coefficient r> 0. 999.The limits of detection(LOD)and limits of quantification(LOQ) were 0.16—0. 31 μg/kg and 0.52—1.01 μg/kg,respectively. The average recoveries ranged from 77.72% to 102.79% with relative standard deviation(RSD)of 1.07—8.92% at three different supplemental concentrations. In summary,this method has the advantages of simple operation,stability,reliability,and low detection cost,which can be used for the detection of fumonisins in corn.
