Abstract

In order to establish determination method of 7kinds of sulfonylurea herbicides in soybean.Samples were extracted with acetonitrile,defatted with hexane,cleaned with HLB SPE,and then detected by UPLCMS/MS with external standard method of quantitative.The results showed that the linear range was 50~300μg·L-1,the correlation coefficients was above 0.99.The average recovery ranged from 71.2% to 91.5%,and the relative standard deviations below 10%,which could be accepted to determine the sulfonylurea herbicides in soybean.
