超高效液相色谱法测定酱油中黄曲霉毒素B1，B2，G1，G2的含量

摘要

This study uses ultra high performance liquid chromatograph,equipped with FLR detector with Mycosep 226 multifunctional purifying column to determine Aspergillus flavus toxin B1 ,B2 , G1 ,G2 in soy sauce,the recoveries are 83%~105%,the minimum detection limits are 0.25μg/kg, the correlation coefficients are all more than 0 .9 9 9 ,the RSDs are 2 .2%~6 .9%,the purifying effect is good.The method is rapid,simple and accurate,and can be widely used in routine testing.%研究采用超高效液相色谱仪，配有FLR 检测器，采用 MycoSep 226多功能净化柱对酱油中的黄曲霉毒素B1，B2，G1，G2进行测定，得到回收率在83％～105％之间，最小检出限为0．25μg／kg，相关系数均为0．999以上，RSD为2．2％～6．9％，净化效果好。该方法快速、简单、定量准确，能够广泛应用于日常检测工作中。
