In last years, a plethora of extraction techniques has emerged as environmental-friendly alternatives to conventional extraction procedures. In this particular field, a novel class of solvents known as deep eutectic solvents (DES) has arisen as a new and very promising tool. Compared with conventional organic solvents, DES as well as the so-called natural deep eutectic solvents (NADES) have attracted considerable attention due to the fact that they not only are eco-friendly, non-toxic, and biodegradable organic compounds but also have a low cost, being easy to produce in the own laboratory. The present review provides a critical and organized overview of novel extraction techniques using DES as extracting solvents that were applied in food, biological and environmental sample analysis. An evaluation of how these DES/NADES could improve extraction yields of a variety of analytes and advantages and limitations of each proposal will be discussed and compared with earlier studies.

近年来，大量提取技术作为传统提取程序的环保替代品出现了。在这个特定领域中，已经出现了一种新型的称为深共熔溶剂（DES）的溶剂，它是一种新的，非常有前途的工具。与常规相比DES和所谓的天然深共熔溶剂（NADES）不仅引起人们的关注，因为它们不仅是环保，无毒且可生物降解的有机化合物，而且成本低廉，易于在自己的实验室中生产。本综述提供了使用DES作为提取溶剂的新颖提取技术的重要而有条理的概述，这些提取技术已应用于食品，生物和环境样品分析。将讨论对这些DES / NADES如何提高多种分析物的提取率以及每种方法的优点和局限性的评估，并将其与早期研究进行比较。
