Choice of extraction procedure to be applied. Chloroform, ethanol, and methanol are the most often utilized solvents in . The extractor only works when the solute being extracted has limited solubility in the solvent in which it is dissolved. The Soxhlet extraction follows the principle of backflow and siphon of the solvent, and makes continuous extraction of the needed components in the solid and liquid mixture. Fix the lower end of the soxhlet extractor to the flask underneath. The ASE and Soxhlet extraction techniques presented the highest yields of volatile and phenolic compounds, showing their suitability to characterise the chemical profile of aromatic plants. A soxhlet-type extraction efficiently removes contaminants with a low use of solvents and techni-cian time. A wide variety of solvents like dichloromethane (DCM), pure or mixed with acetone or hexane, and acetone-hexane mixtures can be used. This presentation will provide an introduction to the practice of soxhlet With the increasing demand for herbal medicinal products, nutraceuticals, and natural products for primary healthcare worldwide, medicinal plant extract manufacturers and essential oil producers have started using the most appropriate extraction techniques. The Soxhlet extraction has widely been used for extracting valuable bioactive compounds from various natural sources.
