| 摘 要： | 建立超高效液相色谱串联质谱法测定香蕉中的三唑醇残留的方法。样品中三唑醇经乙睛提取,氟罗里硅土小柱净化,以C18反相柱为分析柱,甲醇-0.05%甲酸溶液为流动相,采用超高效液相色谱-串联质谱多反应监测,电喷雾正电离源(ESI+),外标法定量。三唑醇在0～0.16mg/L范围内均与峰面积呈良好线性关系,相关系数为0.9991。香蕉中三唑醇的最低检出限为1.0μg/kg,回收率为87.8%～97.8%,相对标准偏差为4.8%～10%。结果表明该方法简便、快速、灵敏,适合香蕉样品中的三唑醇残留分析。

| Abstract: | In order to establish a method for determining triadimenol residues in banana by ultra-performance liquid-chromatography-mass spectrometry(UPLC-MS/MS),the triadimenol residues in samples were extracted with acetonitrile,cleaned up ony Florisil SPE column,separated on C18 reverse phase column using methanol-0.05% formic acid as mobile phase,and detected with positive ionization electrospray ionization-mass spectrometry under a multiple reaction monitoring(MRM) mode.An excellent linear relationship between tr... |
