PG - 1-7 LID - S1570-0232(14)00165-2 [pii] LID - 10.1016/j.jchromb.2014.03.003 [doi] AB - A gas chromatographic method for simultaneous determination of 50 organochlorine (OCP) and pyrethroid (PP) pesticides in Flos Chrysanthemi was established. Accelerated solvent extraction (ASE) technique was used to extract the target compounds, cleaned with alumina neutral-florisil column, and eluted by mixed solvents of ethyl acetate and hexane (15:85, v/v). Selected pesticides were identified using HP-5 and DB1701 capillary dual column and detected by electron-capture detector. Quantitative analysis was performed using an external standard by HP-5 capillary column. Results showed that recoveries were 73.4-120.1%, and the relative standard deviations (RSDs) were 1.6-12.4%. The limits of detection of the method were 0.0021-0.0069 mg/kg, and the limits of quantity were 0.0064-0.0210 mg/kg. CI - Copyright (c) 2014 Elsevier B.V. All rights reserved.
