[0045] (2) Soaking: add 15 kg of deionized water, the residue extracted more than 6 times into the soaking solution of step (1) and soak for 24 hours. Soak 6 times;
[0046] (3) Filtration: Filter out the soaking liquid soaked with residue with 8 layers of gauze:
[0047] (4) Concentration: Adjust the filtrate to PH=7 with concentrated HCL, and concentrate it in a water bath at 80°C until it becomes viscous and hangs on the wall;
[0048] (5) Alcoholprecipitation: add the concentrated filtrate to four times the volume of 90% ethanol solution, stir constantly, and then stand still for 12 hours;
[0049] (6) Drying: After centrifugation (3000pm), the precipitate is routinely dried to obtain the crude polysaccharide extracted with alkali.
[0050] (7) Extraction of alkali-extracted water-soluble crude polysaccharide: add the crude polysaccharide that has not been completely dried by alkali-extracted polysaccharide into deio...

Abstract
The present invention discloses dauricine polysaccharide and its extraction method and the use of medicine with the compound as active component. Asiatic moonseed stem is crushed and water decocted; the residue after water extraction is soaked in alkali solution for 24 hr, alkali solution extracted for 3-6 times; the filtrate is pH regulated with acid liquid to 7 and concentrated in water bath at 80 deg.c; the precipitate is dissolved in distilled water and centrifugal for 3-4 times to obtain precipitate; and the precipitate is dried to obtain dauricine polysaccharide. The dauricine polysaccharide may be used in preparing medicine for auxiliary treatment of primary cancer in the early and middle stages and for clearing away the heat of pharynx and larynx.
Description
Technical field: [0001] The invention relates to a polysaccharide substance, the compound is a new substance extracted from the traditional Chinese medicinePuerariajaponica, specifically, it is a polysaccharide derived from dauricine, and at the same time it discloses its preparation method and the medicinal use of the compound as an active ingredient, belonging to The technical field of extraction of effective components of traditional Chinese medicine. Background technique: [0002] Bat kudzu is a plant of Fangjiaceae, which is recorded in the Pharmacopoeia. The root of the plant is mainly used for tonsillitis, laryngitis, mumps, jaundice, bronchitis, pneumonia, enteritis, dysentery, and pyelonephritis. Since bat kudzu preparations have obvious anti-inflammatory and tumor-inhibiting effects, and polysaccharides have this function, it is of great significance to separate and purify water-soluble polysaccharides by alkali extraction, study their structure, and determine th...
