Abstract
The invention provides a method for extracting and preparing total polysaccharide of compound abnormal savda munziq; wherein, the compound abnormal savda munziq is prepared by ten traditional Chinese medicinal materials including microcos fruit, oxtongue, liquorice, capillaire and humifuse euphorbia by certain proportion; the medicinal materials are decocted, soaked, filtered, concentrated by decompressing and dried into solid extractum which is crushed into the dry powder. The dry powder is dissolved in hot water and filtered; the filtrate goes through macroporous resin and is eluted with water; the eluant is concentrated and decolored and purified by active carbon and filtered; the purified eluant is concentrated by decompressing; after cooling, the filtrate is added with ethanol, stirred and settled to form precipitate which is added with hot water, stirred and re-dissolved and the solution is then filtered when being hot; the filtrate is concentrated and added with ethanol after cooling for settlement, followed by the stirring and settlement of the filtrate, and the filtering; the obtained filtrate is dried and finally the total polysaccharide product is obtained with the purity of over 50percent. The extraction and preparation method is characterized by low cost, simplicity, practicality and safety, and the prepared total polysaccharide can be prepared into capsules, tablets, oral liquid, granules, medical potion, syrup and pills.
Description
technical field [0001] The invention relates to the extraction and preparation of total polysaccharides, especially the improvement of purity and method, and is especially suitable for the extraction and preparation of total polysaccharides of a compound abnormal black bile maturation agent. Background technique [0002] Abnormal black gallbladder ripening agent is a compound preparation of Uyghur medicine prepared in proportion with ten kinds of medicinal materials such as ragwort, Buglossus, licorice, maidenhair fern, and chrysanthemum grass, and then decocted, soaked, filtered, and diluted. , mainly used for the treatment of tumors, diabetes, hypertension, coronary heart disease and other intractable diseases caused by abnormal black gallbladder syndrome; Accumulate to the intestinal mucosa, and then use the abnormal black gallbladder to excrete the abnormal black gallbladder accumulated in the intestinal mucosa, so as to achieve the purpose of treating the disease. This...
