摘要

背景:槟榔叶(Piper betel)中存在不良物质,包括农药(异种生物制剂),是消费者非常关注的问题,因为它是直接咀嚼和食用的。为了保护消费者的健康,开发了一种改进的QuEChERS方法,用于监测目的和随后的净化过程。目的:建立槟榔叶中非允许有机磷农药残留的多残留分析方法,并建立具有成本效益的清洁策略。方法:采用改良的QuEChERS法,用乙腈提取匀浆后的15 g槟榔叶样品(20份采自印度西孟加拉邦),重组为丙酮,最后进行GC-MS/MS分析。评估了可能的去污技术(如自来水洗涤、2%盐水洗涤和温水洗涤)。结果:检出限为0.003 ~ 0.005 mg/kg,定量限为0.01 mg/kg。加样回收率为80% ~ 120%,rdr为9%。其中一个样本含有三种农药,比最大残留限量高出4至7倍。建议的净化方法可以将有毒物质减少到欧洲限值以下。结论:该方法可用于槟榔叶中农药残留的快速测定。传统的槟榔叶加工技术可以将农药残留量降低到规定限度以下。重点:采用QuEChERS-GC-MS/MS技术对槟榔叶中农药进行了多残留分析和去污,方法性能满意。国内净化技术在减少槟榔叶农药残留方面效果显著,使槟榔叶可安全食用。

Simultaneous Monitoring and Decontamination of Pesticide Residues in Phytomedicine-Enriched Betel Leaf Utilizing QuEChERS-GC-MS/MS Technology to Safeguard Public Health.

Background: The presence of undesirable substances, including pesticides (xenobiotics) in betel leaf (Piper betel), is a great concern for consumers because it is chewed and consumed directly. To protect the consumer's health, a modified QuEChERS method for monitoring purposes and subsequent decontamination process has been developed.

Objective: The goal of this work was to establish a multi-residue analytical method for monitoring nonpermitted organophosphorus pesticide residues in betel leaf, as well as cost-effective cleaning strategies.

Method: The homogenized 15 g samples (20 betel leaf samples collected in West Bengal, India) were extracted with a modified QuEChERS method using acetonitrile, reconstituted to acetone, and finally analyzed by GC-MS/MS. Possible decontamination techniques (such as tap water washing, 2% saltwater washing, and lukewarm water washing) were evaluated.

Results: The limit of detection ranged from 0.003 to 0.005 mg/kg, and limit of quantification was 0.01 mg/kg. Recoveries ranged from 80 to 120% with RSDr 9%. One sample was found to contain three pesticides 4 to 7 times higher than MRLs. Suggested decontamination methods allowed reducing toxic traces below European limits.

Conclusions: The suggested approach is useful for determining pesticide residues in betel leaves quickly. Traditional techniques of processing betel leaves may reduce pesticide residues below regulatory limits.

Highlights: A multi-residue method and decontamination of pesticides in betel leaf using QuEChERS-GC-MS/MS technology with satisfactory method performance was achieved. Domestic decontamination techniques have a high efficacy in reducing pesticide residues from betel leaves, making them safe for human consumption.
