摘要

目的:建立QuEChERS-UPLC-MS/MS法测定新疆枸杞中 31 种农药残留的方法.方法:样品经改进后的QuEChERS法净化后,经正负离子分段扫描和多反应监测模式检测,基质匹配标准溶液外标法定量.结果:在 0.001～0.200 mg·L-1,31 种目标化合物的线性相关系数均＞0.996.回收率为 70.2%～111.4%,相对标准偏差≤11.3%,检出限为0.01～7.97 μg·kg-1.结论:该方法快速、简便、准确,具有较强的适用性,可用于含糖量高的枸杞试样中多种农药残留的快速筛查与确证.

Abstract

Objective:To establish a QuEChERS-UPLC-MS/MS method for the determination of 31 pesticide residues in Xinjiang Lycium chinense Miller.Method:The samples were purified by the improved QuEChERS method,detected by the positive and negative ion scanning and multi-reaction monitoring mode,and quantified by matrix matching standard solution external standard method.Result:In the range of 0.001～0.200 mg·L-1,the linear correlation coefficients of 31 target compounds were greater than 0.996,the recoveries were 70.2%～111.4%,the relative standard deviations were less than or equal to 11.3%,and the detection limits were 0.01～7.97 μg·kg-1.Conclusion:The method is rapid,simple,accurate and has strong applicability,and can be used for rapid screening and confirmation of pesticide residues in Lycium chinense Miller samples with high sugar content.
