Harnessing bioactive compounds: Review of emerging extraction technologies

Abstract

Extraction technologies for the recovery of bioactive compounds from natural sources are also important and represent a significant share in different industries such as pharmaceuticals, food or cosmetics. The present review have discussed about various extraction techniques, their principle and merits in noble compounds extractions. The following methodologies are explained in detail including their ability to selectively extract the bioactive compounds with lesser quantity of solvent and environmental friendly viz., Liquid-liquid extraction, Solid Liquid Extraction (SLE) as well as Super Critical Fluid Extraction, SFE), Ultrasound Assisted Extractions. The use of these processes for selective extraction of bioactive compounds such as polyphenols, alkaloids and essential oils is also discussed with special focus on improving the quality and activity of final products. Finally, prospective trends and challenges of such extraction technologies are discussed to provide some future directions for improvements in this field.
