Pesticide residue analysis in olive oil presents difficulties due to the high amount of co-eluted compounds resulting in high matrix effect. Different extraction/clean-up methods including gel permeation chromatography, liquid/liquid extraction, solid-phase extraction and other extraction methods are applied to overcome these difficulties. Recent approaches such as the addition of the freezing-out step and the application of Enhanced Matrix Removal-Lipid sorbent (EMR-Lipid) are reported. Gas chromatography and liquid chromatography coupled to mass spectrometry are considered the gold standard technologies covering a wide scope of pesticides. This review recapitulates the methods most widely used for the determination of pesticide residues in vegetable oils. As a continuation of previous reviews, the work conducted is an update review of methods from 2006 in this field, evaluating their strengths and limitations. Main analytical parameters of the different extraction procedures and detection methods are discussed in terms of recoveries, robustness, limit of quantification, and matrix effect.

由于大量的共洗脱化合物导致了高基质效应，因此橄榄油中农药残留分析存在困难。为了克服这些困难，采用了不同的萃取/净化方法，包括凝胶渗透色谱法，液/液萃取，固相萃取和其他萃取方法。据报道，最近的方法包括增加冷冻步骤和应用增强基质去除脂质吸附剂（EMR-Lipid）。气相色谱和液相色谱与质谱联用被认为是涵盖多种农药的金标准技术。这篇综述总结了最广泛用于测定植物油中农药残留的方法。作为先前评论的延续，进行的工作是对2006年以来该领域方法的最新回顾，评估了它们的优势和局限性。从回收率，稳健性，定量限和基质效应等方面讨论了不同提取程序和检测方法的主要分析参数。
