| 中文摘要:目的：建立菊花中216种常用农药残留的快速检测方法。方法：样品经乙腈高速匀浆提取后浓缩,采用液相色谱-串联质谱(LC-MS/MS)和气相色谱-串联质谱(GC-MS/MS)检测技术,以多反应监测(MRM)模式进行数据采集,采用空白基质匹配法以校准曲线法进行定量检测。结果：菊花中216种农药的线性关系良好,90%以上农药指标相关系数大于0.995,各待测农药指标回收率在70%~115%,符合农药多残留的痕量分析要求；78批菊花中检出农药种类达68种。结论：菊花中农药残留检出率较高、检出品种较多,但检出的多为中低毒性农药。有针对性地检测了菊花中高风险的农药品种,涵盖了绝大多数常用农药,检测方法快速、准确,适用于菊花中多农药残留的风险监测和日常快速筛查,可为基质类似的中药材农药多残留检测方法提供借鉴参考。 |

| Abstract:Objective: To establish a rapid method for the determination of 216 pesticide residues in Chrysanthemum morifolium. Methods: The samples were extracted and concentrated with acetonitrile by high speed homogenate. Detection was performed by LC-MS/MS analysis and GC-MS/MS analysis in multiple reaction monitoring (MRM) mode, and the blank matrix matching method was used for quantitative detection by calibration curve method. Results: The linear relationship of 216 pesticides in Chrysanthemum morifolium was good, the correlation coefficient of more than 90% pesticides was greater than 0.995, and the average recovery rate of each pesticide was 70%-115%, which met the detection requirements of pesticide multi-residue trace analysis. 68 pesticides were detected in 78 batches of Chrysanthemum morifolium. Conclusion: The detection rate of pesticide residues in Chrysanthemum morifolium was higher and more varieties were detected, but most of the detected pesticides were moderate and low toxicity. High-risk pesticide varieties were detected in chrysanthemum morifolium, covering most commonly used pesticides. The detection method was rapid and accurate, which was suitable for the risk monitoring and daily rapid screening of pesticide residues in chrysanthemum. It can provide reference for the detection methods of pesticide residues in Chinese medicinal materials with similar substrates. |
