Apr 17, 2018 · A study on the extraction of catechin (1, Fig. 1) from Arbutus unedo L. fruits using maceration, microwave-assisted and ultrasound extraction techniques showed that microwave-assisted extraction (MAE) was the most effective, but a lower temperature was applied in maceration with nearly identical extraction yields, which can be translated into ...
Extraction theory is a fundamental concept in organic chemistry lab techniques, which explains how solutes partition between two immiscible solvents. This webpage provides a detailed and clear introduction to the principles and applications of extraction theory, with examples and diagrams. Learn how to use extraction theory to optimize your separations and purifications.
Acid-base extraction is a type of liquid-liquid extraction that separates organic compounds based on their acid-base properties. If a solute is an acid or base, its charge changes as the pH is changed. Generally, most organic compounds are neutral, and therefore more soluble in organic solvents than they are in water.

Jan 29, 2020 · If the solvent of extraction is water, maceration is a suitable method but for volatile solvent percolation and Soxhlet extraction are more appropriate.[2,11] (c) Cost of the drug. Cheap drugs are extracted using maceration, whereas costly drugs are preferably extracted using percolation.[2,11] (d) Duration of extraction.
Liquid–liquid extraction, also known as solvent extraction and partitioning, is a method to separate compounds or metal complexes, based on their relative solubilities in two different immiscible liquids, usually water (polar) and an organic solvent (non-polar). There is a net transfer of one or more species from one liquid into another ...
