| 摘 要： | 目的建立了玉米及其制品和小麦及其制品中白僵菌素(beauvericin,BEA)、恩镰孢菌素A(enniatin A,ENA)、恩镰孢菌素A_1(enniatin A_1,ENA_1)、恩镰孢菌素B(enniatin B,ENB)和恩镰孢菌素B_1(enniatin B_1,ENB_1)的高效液相色谱-串联质谱检测方法。方法样品经乙腈-水(85∶15,V/V)提取、室温静置、固相萃取柱净化后,以2 mmol/L乙酸铵水-乙腈作为流动相,采用电喷雾电离正离子多反应监测模式进行检测。结果该方法对玉米及其制品和小麦及其制品中BEA和4种恩镰孢菌素(ENNs)的检出限范围分别为0.01~0.12和0.02~0.21μg/kg,定量限范围分别为0.02~0.44和0.05~0.68μg/kg,平均加标回收率范围分别为91.6%~149.7%和100.5%~128.2%,基质抑制或增强效应分别为88.0%~101.5%和55.8%~106.5%,且BEA和4种ENNs在所测基质中线性关系和精密度良好,相关系数均0.99,相对标准偏差均15%。结论所建立的方法操作简便、灵敏度高、准确性好,可用于玉米及其制品和小麦及其制品中BEA和4种ENNs的测定。
