Recent advances in extraction methods of medicinal plant components

Abstract

Various novel techniques including ultrasound-assisted extraction, microwave-assisted extraction and supercritical fluid extraction have been developed for the extraction of medicinal plants in order to shorten the extraction time, decrease the solvent consumption, increase the extraction yield, and enhance the quality of extracts. This review was conducted to introduce and compare the conventional soxhlet extraction and the new alternative methods used for the extraction of nutraceuticals from plants.
