| 摘 要： | 采用高效液相色谱-串联质谱建立了高效液相色谱-串联质谱法同时测定花生制品中4种黄曲霉毒素（B1、B2、G1、G2）的方法。结果表明,在ESI正离子模式下,高效液相色谱-串联质谱法的最低检出限为0.2μg/kg,定量限为0.6μg/kg;标准工作液在0.5~50.0μg/kg的范围内线性良好,相关系数达到0.9990。

| Abstract: | Liquid chromatography-tandem mass spectrometry was used for the simultaneous quantitative analysis of aflatoxin Bl,B2,G1 and G2 in peanuts.The eluted extract was analyzed by HPLC-MS/MS in positive ion mode using multiple reactions monitoring with a triple-quadruple MS using an electrospray ionization source.The limits of detection（LODs,S/N=3） and the limits of quantification for the target compounds were in the range of 0.2 and 0.6 μg/kg,respectively.The calibration curve was linear in the concentration range of 0.5~50 μg/kg with the regression coefficient of 0.9990. |
