Selective extraction of bioactive compounds from plants using recent extraction techniques: A review

Plant extraction has existed for a long time and is still of interest. Due to technological improvements, it now possible obtain extracts with higher yields. While global yield major parameter because assesses the performance, can be interest focus on particular compounds (specific metabolites) enrich sample avoid unwanted ones, instance primary metabolites (carbohydrates, triacylglycerols). The objective then improve selectivity considered. In solid-liquid extraction, which often called maceration, solvent impact selectivity. Its polarity direct influence solutes extracted, related chemical structure compounds, modelling compound/solvent interactions by using various or interaction scales great challenge favor choice appropriate extracting liquid. Technical advances have allowed development recent, sometimes green, techniques, such as Microwave-Assisted Extraction (MAE), Ultrasound-Assisted (UAE), Pressurized Liquid (PLE) Supercritical Fluid (SFE). This review focuses specificity these recent techniques their physical parameters (i.e. pressure, intensity, etc.). addition selection, prime interest, applied different results in ways. Besides, SFE versatile green technique suitable achieve some compounds. its properties, SC-CO2 allows tailoring conditions
