Abstract

Abstract As a result of massive bee deaths in recent years, beekeeping is raising concerns about the presence of pesticides in propolis which is considered as a safe product. The paper is focused on the analysis of bee propolis and propolis-based products using various chromatographic techniques using mass spectrometry detection predominantly. An important part of the work is an overview concerning methods of sample preparation, extraction, and purification of extracts, followed by separation and detection techniques. Positive findings of contaminants and their concentrations in propolis samples and propolis products were evaluated. Sorption based techniques such as matrix solid phase dispersion and solvent-based extraction techniques are frequently applied for propolis analysis in connection with chromatographic techniques. Liquid-based extractions, such as the QuEChERS extraction technique (Quick, Easy, Cheap, Effective, Rugged, Safe), combine extraction by solvent with several ways of extract cleaning using combinations of salts and sorbents, primary secondary amine, MgSO4, NaCl, graphitized carbon, EMR-lipid, florisil, or octadecylsilane-modified silica gel. Other extraction techniques were reviewed. The most significant problem to be considered in pesticides detection is the topic of matrix effects, which have to be solved for each sample analysis with special care.
蜂胶和蜂胶基产品中农药残留测定的分析方法
近年来,由于蜜蜂大量死亡,养蜂人对蜂胶中农药的存在感到担忧,蜂胶被认为是一种安全的产品。本文主要介绍了蜂胶和蜂胶基产品的各种色谱分析技术,以质谱检测为主。该工作的一个重要部分是概述了样品制备,提取和提取纯化的方法,其次是分离和检测技术。对蜂胶样品和蜂胶制品中的污染物及其浓度进行了评估。以吸附为基础的技术,如基质固相分散和溶剂萃取技术,经常与色谱技术相结合,用于蜂胶分析。液体萃取,如QuEChERS萃取技术(快速、简单、廉价、有效、坚固、安全),结合溶剂萃取和几种萃取清洗方法,使用盐和吸附剂、仲胺、MgSO4、NaCl、石墨化碳、emr -脂质、florisil或十八烷基硅烷改性硅胶的组合。对其他提取技术进行了综述。在农药检测中需要考虑的最重要的问题是矩阵效应,这是每个样品分析都必须特别注意解决的问题。
