Abstract

Abstract:

A HPLC method was developed for the determination of chlorfluazuron residue in cabbage. Samples were extracted with ethyl acetate and cleaned up on Florisil column prior to HPLC analysis. The limit of detection of the method was 1.2 ng. At three spike levels (0.05, 0.5, 2 mg/kg), the recoveries of chlorfluazuron ranged from 81.95% to 100%, with coefficients of variation ranging from 2.37% to 6.21%. The figures of merit of this method can meet the requirements of pesticide residue analysis and therefore benefit its application in the determination of chlorfluazuron residue in cabbage.

Key words: chlorfluazuron, cabbage, pesticide residue analysis
