摘要

目的: 采用改良的QuEChERS法联合气相色谱-质谱技术

建立一种快速检测人参提取物中25种农药残留的分析方法. 方法: 样品以乙腈提取

经氯化钠、无水硫酸镁盐析后

上清液加入乙二胺-N-丙基硅烷和石墨炭黑分散固相萃取剂进行净化

并采用基质匹配标准曲线法进行定量分析. 结果: 异狄氏醛

p'-滴滴涕和甲氧滴滴涕在人参提取物中表现出相对较强的基质效应(ME >130%)

而对硫磷则呈显著的基质效应(ME >150%)

采用基质匹配标准曲线法校正后

25种农药在0.01~1 mg·L-1线性关系良好

Abstract

Objective: To establish the chromatographic method for rapid determination of 25 pesticide residues in Ginseng extract by QuEChERS-GC-MS. Method: The samples were extracted with acetone which included acetonitrile

the sodium chloride

anhydrous magnesium sulfate salting out process

and cleaned up by PSA and GCB

and reduced the matrix effect by Matrix matched standard curve method. Result: The endrin aldehyde

p'-DDT

methoxychlor showed relatively strong matrix effects(ME >130%)

and parathion showed strong matrix effects (ME >150%)

after the correction of matrix calibration curve

the linear range was 0.01-1 mg·L-1 and r >0.995 4

the recovery range was 81.8%-110.7% in 3 adding level (0.1

0.5

1.0 μg·g-1)

RSD<15%

LOQ was 3-48 μg·kg-1. Conclusion: The method is accurate

sensitive and suitable for the determination of pesticide residues in ginseng extract.
