摘要

目的：基于气相色谱-串联质谱联用技术，建立GC-MS/MS农药多残留筛查与检测方法；在满足农药残留量检测方法学考察的技术要求基础上，对陈皮中179种农药残留量进行筛查与检测，全面了解陈皮种植过程中农药使用情况，以及陈皮药材的农药残留量。方法：陈皮样品先经2次乙腈匀浆提取，过固相萃取柱（SPE）净化，浓缩，滤过，加内标分析保护剂，采用GC-MS/MS技术进行检测。结果：建立了179种禁用、限用、高毒、国内常用农药指标的GC-MS/MS测定法；针对陈皮基质，建立了满足方法学要求的提取、净化、测定方法，该提取净化方法回收率在60%～120%，RSD≤15%，方法检出限总体在0.01 mg·kg-1以下。结论：建立的农药多残留方法指标较全面，有针对性，且方法灵敏度高，准确性好，可广泛地筛查与检测陈皮中农药多残留量，从而全面地反映农药污染情况；筛查结果表明，陈皮种植中农药使用种类较多，农药残留污染情况比较严重，陈皮药材的使用存在农药残留量超标风险。

Abstract

Objective: To establish a GC-MS/MS method for detecting 179 pesticides in Citri Reticulatae Pericarpium

in order to find out the current situations of pesticide residues in Citri Reticulatae Pericarpium. Method: The samples were extracted with acetone for twice

cleaned up by solid-phase extraction (SPE)

concentrated

filtered

added with internal standard analysis protection agent

and then determined by GC-MS/MS. Result: The method of GC-MS/MS was established for determining 179 pesticides

including forbidden

limited

high-toxic and common pesticides. The recoveries of most pesticides ranged from 60% to 120%

with RSDs less than 15%. The limits of determination were below 0.01 mg·kg-1. Conclusion: This method is sensitive and accurate

and can be used for the determination of multi-residual pesticides in Citri Reticulatae Pericarpium. The findings show that many finds of pesticides were used in planting oranges

which causes serious pesticide residues pollution. Therefore

there is a risk of using Citri Reticulatae Pericarpium with excessive pesticide residues.
