| Abstract：A reversed phase HPLC was applied for determing the active ingredients of 30% Mefenacet-bensulfron-acetochlor mixed powder.Taking acetonitrile,methanol and water of 30∶40∶30 as the mobile phase at UV-230?nm ,SD and CV of the method for mefenacet, bensalfron and acetochlor are 0.038,0.15%,0.015,0.59% and 0.016,0.63%. The recovery is 98.1%～102.28%. |
