Abstract:
Extraction of bioactive chemicals from plant material is a crucial step in the separation and purification process. Traditional methods such as Soxhlet, heat reflux, and maceration have limitations, leading to the emergence of novel technologies that offer several advantages, including higher extraction yields, preservation of thermo-sensitive structures, and the use of non-organic solvents. These emerging technologies, such as high hydrostatic pressure, pulsed electric fields, and supercritical fluids, enhance mass transfer rates, increase cell permeability, and improve secondary metabolite diffusion, resulting in high-quality extracts with fewer impurities. This research aims to investigate the impact of these emerging extraction methods on the individual profile of bioactive chemicals in plant material.
