Green solvents for the extraction of bioactive compounds from natural products using ionic liquids and deep eutectic solvents

Green technology is moving from an option to a must in modern industrial processing. Solvents are the core of the food, pharmaceutical, cosmetic, agrochemical, chemical, and biotechnological process technologies. In the past two decades, supercritical fluids, ionic liquids, and deep eutectic solvents became the most actively investigated as potential green solvents, especially in the field associated with food, flavors, fragrances, and medicinal plants processing. This review assesses recent information about the novel solvent technologies.
