A liquid chromatographic (LC) method is proposed for the determination of aflatoxin M1 in milk. The method was successfully applied to both liquid whole and skim milk and also whole and skim milk powder. The samples are initially extracted with acetonitrile-water followed by purification using a silica gel cartridge and a C18 cartridge. Final analysis by LC was achieved using a radial compression module equipped with a 5 micron C18 column and a fluorescence detector. The method was successfully applied to samples at levels of 10 to 0.08 ppb added aflatoxin M1 with recoveries in the range of 70-98%.
提出了一种用于测定牛奶中黄曲霉毒素M1的液相色谱（LC）方法。该方法已成功应用于全脂液态奶和脱脂液态奶，以及全脂奶粉和脱脂奶粉。样品首先用乙腈 - 水进行萃取，然后使用硅胶柱和C18柱进行净化。通过配备5微米C18柱和荧光检测器的径向压缩模块进行液相色谱最终分析。该方法已成功应用于添加了浓度为10至0.08 ppb黄曲霉毒素M1的样品，回收率在70 - 98%范围内。
