摘要
Phenolics are organic compounds which contain a phenol ring and one or more hydroxyl groups. These molecules are produced as secondary metabolites and are ubiquitous in all plant tissues. Besides, the consumption of phenolic compounds has been associated with the promotion of human health. Therefore, the extraction of these molecules has been of great interest for many researches and could be used for food and pharmaceutical purposes. Agro-industrial by-products are rich in many phytochemicals, such as phenolic compounds. These by-products are generated from fruit and vegetable processing and have been mainly regarded as wastes. Thus, there is a need to revalorize these by-products. Recently, the research have been focusing of the identification and quantification of phenolic content from agro-industrial by-products, the maximization of the yield of recovery of phenolic compounds assessed by different methods of extraction, and the enhancement of the concentration of phenolic compounds. Thus, this chapter describes the extraction of phenolics from agro-industrial by-products by different methodologies, as well as the enhancement of the phenolic content and their biological properties.

酚类是含有酚环和一个或多个羟基的有机化合物。这些分子作为次生代谢产物产生，并在所有植物组织中普遍存在。此外，食用酚类化合物与促进人类健康有关。因此，这些分子的提取已引起许多研究的兴趣，可用于食品和药物目的。农业工业副产品富含许多植物化学物质，例如酚类化合物。这些副产品是从水果和蔬菜加工中产生的，主要被视为废物。因此，需要重新评估这些副产品。近年来，研究集中在从农副产品中鉴定和定量酚含量，通过不同提取方法评估的酚化合物回收率的最大化以及酚化合物浓度的提高。因此，本章介绍了通过不同方法从农副产品中提取酚类，以及酚类含量及其生物学特性的提高。
