Neonicotinoids (NEOs) are the most widely used insecticides globally. They can contaminate or migrate into foodstuffs and exert severe neonic toxicity on humans. Therefore, lots of feasible analytical methods were developed to assure food safety. Nevertheless, there is a lack of evaluation that the impacts of food attributes on the accurate determination of NEOs. This review aims to provide a comprehensive overview of sample preparation methods regarding 6 categories of plant-derived foodstuffs. Currently, QuEChERS as the common strategy can effectively extract NEOs from plant-derived foodstuffs. Various enrichment technologies were developed for trace levels of NEOs in processed foodstuffs, and multifarious novel sorbents provided more possibility for removing complex matrices to lower matrix effects. Additionally, detection methods based on liquid chromatography were summarized and discussed in this review. Finally, some limitations were summarized and new directions were proposed for better advancement.
新烟碱类杀虫剂（NEOs）是全球使用最广泛的杀虫剂。它们会污染或迁移到食品中，并对人类产生严重的新烟碱毒性。因此，人们开发了许多可行的分析方法来确保食品安全。然而，目前缺乏关于食品属性对准确测定新烟碱类杀虫剂影响的评估。本综述旨在全面概述6类植物源食品的样品制备方法。目前，QuEChERS作为常用策略能够有效地从植物源食品中提取新烟碱类杀虫剂。针对加工食品中痕量新烟碱类杀虫剂开发了各种富集技术，多种新型吸附剂为去除复杂基质以降低基质效应提供了更多可能性。此外，本综述还总结并讨论了基于液相色谱的检测方法。最后，总结了一些局限性，并提出了新的方向以实现更好的进展。
