|
The analysis method for qualitative analysis of the screening method that can be performed prior to the quantitative analysis of individual pesticide was reviewed in order to meet the safety standards that are being strengthened in the field of pesticide residue testing of herbal medicines. Among the residual pesticides presented in the Korean Pharmacopoeia, 56 pesticides, excluding 15 pesticides that need to be individually analyzed, were selected for analysis using QuEChERS preprocessing and GC-MS/MS, which are used in the existing agricultural products field. For each pesticide, the detection limit level of 0.001-0.005 mg/kg and the quantitative limit level of 0.002-0.017 mg/kg were confirmed. In the recovery test in which the standard was treated at a concentration of 0.02 mg/kg, it was confirmed that the proportion of pesticides satisfying the recovery of 70-120% was 85.7-96.4% for each herbal medicine, so it was confirmed that it was a level that could be reviewed by the screening method.
