In this work, a green analytical method was established for the simultaneous extraction and detection of 20 analytes-10 neonicotinoid insecticides and their 10 major toxic metabolites in edible herbs. QuEChERS and LC-MS/MS were used to analyze the 20 analytes in five edible herbs. The residues of the 20 neonicotinoid insecticides and their metabolites in 109 herbal samples were detected, of which 90 samples were positive, and the residue of total neonicotinoid insecticides ranged from 0.26 to 139.28 μg/kg. Acetamiprid (77.06 %, ≤85.95 μg/kg), imidacloprid (67.89 %, ≤32.49 μg/kg) and their metabolites (-desmethyl-acetamiprid (44.04 %, ≤18.42 μg/kg) and desnitro imidacloprid (48.62 %, ≤16.55 μg/kg) were most frequently detected in herbs. Significant positive correlations were found between imidacloprid/acetamiprid and their metabolites in and . Therefore, more attention may be given to the neonicotinoid insecticide residues in edible herbs in the future.
在本研究中，建立了一种绿色分析方法，用于同时提取和检测食用草药中的20种分析物——10种新烟碱类杀虫剂及其10种主要有毒代谢物。采用QuEChERS和液相色谱-串联质谱法分析了5种食用草药中的20种分析物。检测了109份草药样品中20种新烟碱类杀虫剂及其代谢物的残留量，其中90份样品呈阳性，新烟碱类杀虫剂的总残留量为0.26至139.28μg/kg。啶虫脒（77.06%，≤85.95μg/kg）、吡虫啉（67.89%，≤32.49μg/kg）及其代谢物（去甲基啶虫脒（44.04%，≤18.42μg/kg）和去硝基吡虫啉（48.62%，≤16.55μg/kg）在草药中最常被检测到。在[具体内容缺失]中，吡虫啉/啶虫脒与其代谢物之间存在显著正相关。因此，未来可能需要更多关注食用草药中的新烟碱类杀虫剂残留。
