摘要:

建立了一套检测食品中杀草强的液相色谱及液相色谱- 质谱分析方法,采用高效液相色谱荧光检测器(LCFLD),在激发波长380nm、发射波长484nm 条件下,高效液相色谱串联四级杆质谱配大气压电离源(LC-MS/MSAPCI),在多反应监测(MRM)模式下,母离子m/z 85、定量子离子m/z 43、定性子离子m/z 57、碰撞能量m/z85 > m/z 57 为56.9/11eV、m/z 85 > m/z 43 为58.1/11eV、裂解电压100V 条件下,分别对杀草强残留量进行检测,其中液相色谱荧光检测器法杀草强的检出限0.01mg/kg;液相色谱串联质谱法杀草强的检出限为0.005mg/kg。该方法简便、快速,分析结果准确、可靠,两种仪器条件可灵活选择,适用于食品中杀草强残留量的快速检测。

Abstract:

High-performance liquid chromatography with fluorescence detection (HPLC-FLD) and high performance liquid chromatography-atmospheric pressure chemical ionization-tandem mass spectrometry (HPLC-APCI-MS/MS) were used for analyzing amitorle residue in plant-derived foodstuffs. In HPLC-FLD analysis, the excitation wavelength and emission wavelength were set at 380 and 484 nm, respectively. HPLC-APCI-MS/MS analysis was carried out in the MRM mode under the conditions as follows: parent ion, m/z 85; quantitative daughter ion, m/z 43; qualitative daughter ion, m/z 57; collision energy, m/z 85 > m/z 57 to 56.9/11 eV, m/z 85 > m/z 43 to 58.1/11 eV; and cracking voltage, 100 V. Limit of detection was 0.01 mg/kg for HPLCFLD method and 0.005 mg/kg for HPLC-APCI-MS/MS method. Both methods demonstrate the advantages of simplicity, rapidity, accuracy and reliability and are alternatives to each other for the determination the determination of amitorle residue in plant-derived foodstuffs.

Key words: high performance liquid chromatography with fluorescence detection (HPLC-FLD), high performance liquid chromatography-atmospheric pressure chemical ionization-tandem mass spectrometry (HPLC-APCI-MS/MS), amitorle residue
