本文综合国标法，色谱法及试剂盒法三种方法进行修正，把1:1的甲醇水改为7:3的甲醇水直接加进样品中，删除国标法及试剂盒自带方法中采用石油醚转移步骤，把手动振摇、蒸发等步骤改为漩涡振荡及离心方法，改良了样品的提取方法，操作方便，减少交叉污染，使结果更稳定。

In this paper, three methods, including GB method, chromatography method and reagent box method, were corrected for detection of Aflatoxin B1content The ratio of methanol to water (1: 1) was changed to 7: 3 methanol water. And the mixture was directly added into the sample. The petroleum ether-transferation step was removed from the GB and reagent kit methods. The manual shaking and evaporation were changed to vortex oscillation and centrifugal method, respectively. The sample extraction method was also improved to be more convenient, , to reduce the pollution and to make the result more stable.
