Abstract

The analytical method to determine organochlorine pesticides in natural medicines included in The Japanese Pharmacopoeia (JP), 15th edition,¹⁾ is not adequate because the recovery rates of organochlorine pesticides in Glycyrrhizae radix are very low. In this study, we developed a method to analyze organochlorine pesticides in Glycyrrhizae radix with acceptable recovery rates. The method enables analysis of organochlorine pesticides in all natural medicines for which maximum residue levels are set.
