Abstract

From all the valuable biomass extractives, polyphenols are a widespread group of secondary metabolites found in all plants, representing the most desirable phytochemicals due to their potential to be used as additives in food industry, cosmetics, medicine, and others fields. At present, there is an increased interest to recover them from plant of spontaneous flora, cultivated plant, and wastes resulted in agricultural and food industry. That is why many efforts have been made to provide a highly sensitive, efficiently, and eco-friendly methods, for the extraction of polyphenols, according to the green chemistry and sustainable development concepts. Many extraction procedures are known with advantages and disadvantages. From these reasons, the aim of this article is to provide a comparative analysis regarding technical and economical aspects related to the most innovative extraction techniques studied in the last time: microwave-assisted extraction (MAE), supercritical fluid extraction (SFE), and ultrasound-assisted extraction (UAE).
