建立了邻苯二甲醛(OPA)柱后衍生-高效液相色谱测定玉米中伏马菌素B1和B2(FB1和FB2)的方法.采用ZORBAX SB-C18色谱柱,以0.1 mol/L磷酸二氢钠溶液(pH 3.3)-甲醇为流动相,梯度洗脱.流动相流速为0.8mL/min,柱温40℃;衍生剂的流速为0.4 mL/min,衍生温度为室温.实验对衍生剂缓冲液的pH、衍生剂的浓度和流速、激发和发射波长等重要条件进行了优化.结果表明,衍生剂的pH在10.5、OPA的质量浓度为2 g/L、流速为0.4 mL/min、激发波长335 nm、发射波长440 nm时测定效果良好,FB1、FB2在0.2~20 mg/L范围内线性关系良好,相关系数大于0.999;FB1和FB2的检出限均为0.02 mg/kg;在0.1~4.0 mg/kg范围内,3个添加水平的平均回收率为82.5% ~89.8%.该方法精确、简单、快速,适合玉米中FB1和FB2的测定.
