The basic procedure calls for a solid sample to be placed in a porous container and allowing condensed solvent to extract co ntinuously. The Soxhlet extraction process ensures intimate contact of the sample matrix with the extraction solvent. This method is applicable to the isolation and concentration of water-insoluble and slightly water soluble organics in preparation for a variety of chromatographic procedures. The S oxhlet extraction process ensures intimate contact of the sample matrix with the extraction solvent. This method is applicable to the isolation and concentration of water-in soluble and slightly water soluble organics in preparation for a variety of chromatographic procedures. The extraction procedure involves soaking the crude drug, in the form of either a powder or a decoction (kasaya), for a specified period of time, during which it undergoes fermentation and generates alcohol in situ; this facilitates the extraction of the active constituents contained in the plant material. To close the yellow note, click once to select it and. Because of commercial regulations, it is important for food producers to be able to report fat content in a serving size of a food item.
