Bupirimate in agricultural products was extracted and concentrated with acetonitrile, and purified using solid phase extraction column. Then it was detected with GC-MS and quantified with external standard method. The limit of quantification was 0.01 mg/kg, and the recovery was in the range of 70.0% - 89.5% with the relative standard deviation at 6.11%.
