Determination of 20 organochlorine pesticide residues in Panacis Japonici Rhizoma by gas chromatography

doi:10.3969/j.issn.1000-1565.2016.05.007

Abstract

Abstract: A method for the simultaneous determination of 20 organochlorine pesticide residues in Panacis Japonici Rhizoma was developed by gas chromatography with electronic capture detector.The samples were extracted by ultrasonic wave and purified by Florisil.The internal standard method was used in the quantitative analysis.The average recoveries of 3 standard addition levels were 68.21%~124.5%,with relative standard deviations less than 5.64%.The detection limits were 0.009 9~0.049 3 μg/kg.The method is rapid,sensitive and accurate,and it can be applied to the determination of 20 organochlorine pesticide residues in Panacis Japonici Rhizoma.

Key words: gas chromatography, organochlorine pesticides, Panacis Japonici Rhizoma
