Scope

Main technical content: This method is designed for the detection of carbofuran residues in traditional Chinese medicines. Representative traditional Chinese medicines with high risk of carbofuran pesticide residues were selected as the applicable matrices, including wolfberry, mint, honeysuckle, Codonopsis pilosula, and angelica. According to the "Technical Guidelines for the Evaluation of Food Rapid Detection Methods" (Food and Drug Administration Office [2017] No. 43), the minimum detection level (detection limit) for substances subject to national standard limits should be less than or equal to the limit specified in the standard. Therefore, the detection performance (qualitative limit) of this method is set according to the quantitative limit specified in the "Chinese Pharmacopoeia" 2020 Edition, Part IV, Section 0212, "General Standards for the Identification of Medicinal Materials and Herbal Pieces". The detection limits for wolfberry, mint, honeysuckle, Codonopsis pilosula, and angelica are set at 0.05 mg/kg. The blank samples used in this study were purchased from the JD.com online shopping platform and samples from farmers' markets. Those wolfberry, mint, honeysuckle, Codonopsis pilosula, and angelica that were confirmed to be free of carbofuran by reference methods were used as negative blank matrices. The positive samples were obtained by directly adding appropriate amounts of standard substances to the blank samples to obtain samples containing target substances at certain concentrations.
