药用植物中残留有机磷农药的定性和定量分析
The Qualitative and Quantitative Analysis of Organophosphate Pesticides in Medicinal Herbs
摘要
Abstract
An analytical method for the determination of 25 kinds of organophosphate pesticide residues in medicinal herbs was established by gas chromatography-flame photometric detection (GC-FPD) and gas chromatography-ion trap mass spectrometry (GC-ITMS). The pesticide residues in samples were extracted with acetone by ultrasonic wave assistant extraction (UAE), and purified by gel permeation chromatography(GPC). GC-ITMS was used as qualitative determination, whereas GC-FPD was used as quantify. This method can simultaneously analyze 25 kinds of organophosphate pesticide residues. When additive levels between 0.01 mg · kg~(-1) and 0.04 mg · kg~(-1) , the range of recovery is between 66.58% and 111.20%, with RSD is between 0.75 % and 8.07%.关键词
