title: Simultaneous analysis of 17 organochlorine pesticides in natural medicines by GC/MS with negative chemical ionization.
abstract: Many methods for the determination of pesticide residues in food have been reported. Although natural medicines should be confirmed to be as safe as food, few methods for the determination of pesticide residues in natural medicines have been reported. In this study, 17 organochlorine pesticides were detected in natural medicines using GC/MS with negative chemical ionization (NCI). GC/MS with NCI can detect halogenated pesticides selectively and thus is suitable for the detection of organochlorine pesticides. This study indicates that GC/MS with NCI is useful for analyzing organochlorine pesticides in natural medicines.
