摘要 基于气相色谱串联质谱技术,本试验建立了一种鲜西洋参中40种农药残留的快速筛查方法。样品用乙腈提取后,经HLB固相萃取法净化,采用动态多反应监测模式采集数据进行定性、定量分析。结果发现,目标残留具有良好的线性关系,相关系数大于0.99;在20、50、100μg/kg 3个不同质量浓度水平下做加标实验,回收率为74.3%~117.1%,相对标准偏差小于15%。该方法样品前处理简单,检测方法高效、准确、灵敏,适用于鲜西洋参产品中多种农药残留的筛选与测定。 A rapid analysis method was developed for the determination of 40 kinds of pesticides in American ginseng by gas chromatography-tandem mass spectrometry(GC-MS/MS).The samples were extracted with acetonitrile,and purified by HLB column.The qualitative and quantitative analysis was carried out by GC-MS/MS with dynamic multiple reaction monitoring(dMRM)model.The experimental results showed that the 40 pesticides in the corresponding linear concentration range had good linear relationship,the correlation coefficients were more than 0.99.In three different concentration levels of 20μg/kg,50μg/kg and 100μg/kg,the average recovery was 74.3%-117.1%with the relative standard deviations less than 15%.The method is simple,effective,accurate and sensitive,and is applicable for the screening and detection of multi-pesticide residues in American ginseng.
