In recent years, several steps forward have been made toward a more sustainable approach for the extraction of bioactive compounds from plant materials based on the application of green extraction principles. It is currently recognized that waste and by-products deriving from agriculture and food industries still contain a wide array of high value-added substances, which can be re-used to obtain new products with various applications in the food, supplement, pharmaceutical, and cosmetic industries. Anthocyanins are a class of these valuable metabolites; they confer the red, violet, and blue color to fruits and vegetables, and scientific evidence has accumulated over the last few decades to support their beneficial effects on human health, in great part deriving from their powerful antioxidant capacity. This review provides a general overview of the most recent green procedures that have been applied for the recovery of anthocyanins from plant-derived wastes and by-products. The most widely used green solvents and the main sustainable techniques utilized for recovering this class of flavonoids from various matrices are discussed, together with the variables that mainly impact the extraction yield.
近年来，基于绿色提取原则的应用，在从植物材料中提取生物活性化合物的更可持续方法方面已经取得了一些进展。目前人们认识到，农业和食品工业产生的废物和副产品仍然含有大量高附加值物质，这些物质可以重新利用，以获得在食品、补充剂、制药和化妆品工业中有各种应用的新产品。花青素就是这类有价值的代谢产物之一；它们赋予水果和蔬菜红色、紫色和蓝色，并且在过去几十年中积累了科学证据来支持它们对人类健康的有益影响，这在很大程度上源于它们强大的抗氧化能力。本综述概述了最近用于从植物源废物和副产品中回收花青素的绿色方法。讨论了最广泛使用的绿色溶剂以及用于从各种基质中回收这类黄酮类化合物的主要可持续技术，以及主要影响提取产率的变量。
