Abstract
Description
Technical field:
[0001] The invention belongs to the technical field of medicine. Background technique:
[0002] At present, the detailed preparation process of Guning Injection is recorded in "Biochemical Pharmacy" published by China Medical Publishing House. Guning Injection is an injection prepared from pig limb bones. The main component is polypeptide or protein peptide , Quantitative analysis of emission spectrum contains trace elements, mainly Ca, Mg, Al, Fe, other trace elements include Mn, Ba, Cu, Pb, Sn, Ti, Zr, etc., the content is about 1μg / ml. The contained ingredients are soluble in water and ethanol below 75%, and can be precipitated by 10 times the amount of acetone. The pH of the aqueous solution is 4 and 8.5 without precipitation. It is stable to heat and does not lose its pharmacological effect when heated for a long time. Its main disadvantages are: ①Adding phenol to inhibit bacteria in the process makes intravenous injection of injection impossible. ② D...

Embodiment Construction
[0016] The process of the present invention is:
[0017] a. Extraction, degreasing, and concentration: Take healthy and fresh pig limb bones, wash, smash, weigh, add water to the raw materials, heat press, filter with gauze, add water to the bone residue, heat press, filter, and combine twice The filtrate is immediately placed in a jacketed pot, passed through cooling water, cooled to room temperature, placed in a cold storage, and transferred to a cold room after cooling to 0-5°C, skimmed off the upper layer of fat, and heated to melt the jelly. Liquid, concentrated or vacuum concentrated to obtain a concentrated solution;
[0018] b. Precipitation and concentration: take the concentrated solution and add ethanol, let it stand for precipitation, remove impurity proteins, obtain the supernatant, and then concentrate in vacuo;
[0019] c. Acidic precipitation and alkaline precipitation: add hydrochloric acid to the above liquid under stirring, adjust to pH value, and heat unde...
