Abstract

An analysis method for determination of cycolxylidin residue in cabbage and soil was established.[Methods] The sample was extracted with acetonitrile,cleaned-up by Florisil and activated carbon,separated with amino column and determined by HPLC-UV.[Results] The average recoveries in cabbage and soil were 78.39-93.13%,77.9-84.59%,and the coefficient of variation were 2.27-6.59%,3.42-5.97% respectively.The limit of detection of cycloxylidin was 0.2 ng,the limit of quantification was 0.01 mg/kg.[Conclusions] The method is simple and reliable,meet with the requirement of pesticide residues analysis,and could be applied for determining cycloxylidin residues in cabbage and soil.
