Composition is very complicated, Chinese herbal medicine contains both active ingredients, and ineffective ingredients and toxic ingredients. To improve the curative effect of Chinese herbal medicine, will do utmost from complex homogeneous or heterogeneous system to extract the effective components, and then through the separation and the impurities in order to reach the purpose of purifying and refining. The Chinese medicine extraction technology of solvent extraction extraction of Chinese herbal medicine to get attention.
Chinese medicine extraction of Chinese herbal medicine extraction technology of solvent extraction method is the use of Chinese herbal medicine in two mutually soluble ( Or slightly soluble) Solubility in solvent or distribution ratio to achieve separation, extraction and purification of a manipulation. This can be used with water miscibility ( Or slightly soluble) Organic solvents from water in the solvent extraction of organic compounds to illustrate. Will contain organic and aqueous solution by organic solvent extraction, organic compounds are allocated between the two liquid phase. Under a certain temperature, the concentration of organic matter in the organic phase and water phase is a constant, the so-called 'distribution law'.
organic matter solubility in organic solvent, generally is greater than in the water solubility, so they can be extracted from the aqueous solution. But unless distribution coefficient greatly, with a extraction is impossible to move all the material into the new in the organic phase. Chinese medicine extraction of Chinese herbal medicine extraction technology of solvent extraction method, if the first to add a certain amount of electrolytes in aqueous solution, Such as sodium chloride) , the use of so-called 'salting out effect', in order to reduce the organic and the content and extraction solvent solubility in the aqueous solution, often can progress extraction effect.
