Supercritical Green Solvent for Amazonian Natural Resources (original) (raw)

Nanotechnology in the Life Sciences, 2020

Abstract

The Amazon is an ecological system that comprises a considerable part of South America and that presents a great biodiversity of plants and fruits. Most of them have bioactive compounds, such as polyphenols and carotenoids, that are associated with the reduced risk of development of various chronic and degenerative diseases. To obtain such substances, the supercritical fluid extraction stands out among other extraction methods due to environmental concerns, since this technology uses green solvents such as carbon dioxide (CO2), water (H2O), and ethanol (EtOH). In this way, the objective of this work was to present the main solvents used in pressurized solvent extraction, as well as the main bioactive compounds obtained in such processes, and their consequent biological applications.
