Description

Utilize the animal lung to extract the preparation technology of heparin sodium crude
The present invention relates to a kind of preparation technology who utilizes animal viscera to extract heparin sodium, particularly a kind of preparation technology who utilizes the pig pulmonis Bovis seu Bubali to extract heparin sodium crude.
Heparin sodium is a kind of anticoagulant efficacy that has, and prevents that tumor focus from shifting and the costly medicine of diffusion.The oozing of blood that is used for the treatment of the nephropathy patient clinically, acute myocardial infarction disease prevents thrombosis, cerebrovascular disease, dermatosis is removed uremic and partner treatment fulminant epidemic encephalitis septicemia that nephropathy forms, nephritis etc.Simultaneously, heparin sodium also has better action at aspects such as blood fat reducing and immunity, and along with it is understood in depth gradually, its medical application enlarges day by day, and supply falls short of demand in market.At present, China utilizes pig small intestine usually, extracts fresh intestinal mucosa liquid, uses traditional salt to separate the explained hereafter heparin sodium, and this preparation method is difficult to carry out scale production because raw material is deficient and technical limitation; Environmental pollution is serious in process of production; And the production cost height, product yield is low, and it is low to tire, and can not satisfy the wilderness demand in market.
The object of the present invention is to provide a kind of productive rate height, the height of tiring, cost is low, and is the preparation technology who extracts heparin sodium crude from the animal lung that raw material is easy to get.
The present invention is achieved in that a kind of preparation technology who utilizes the animal lung to extract heparin sodium crude, it is characterized in that: animal lung homogenize becomes serosity~serosity insulation enzymolysis~enzymolysis solution to filter to collect filtrate~filtrate the is carried out washing and the eluting~clarification filtration~dry heparin sodium crude that gets of ion exchange absorption processings~resin.
Described animal lung homogenize becomes serosity to be meant cleaned animal lung rubbed wears into slurry, adds the entry mixing thereafter under fully stirring and gets serosity, and the addition of water doubly is the best with the 1-1.3 of slurry.
Described serosity insulation enzymolysis is meant and adds gastric enzyme or the agent of pancreatin enzymolysis when the pH value of adjusting serosity is 10-10.5, stirs, and is warming up to 38 ℃-41 ℃, continues to stir, and keeps the pH value 8-8.5 of serosity, 37 ℃ of-40 ℃ of following enzymolysis 3.5-4.5 of temperature hours; Be warming up to 47 ℃-50 ℃ then, keep serosity pH value 8-8.5, add a small amount of enzymolysis agent, continue enzymolysis and got enzymolysis solution in 4.5-5.5 hour.In whole insulation enzymolysis process, adopt sig water such as sodium hydroxide to adjust to the adjustment of serosity pH value; The Pancreas Sus domestica slurry is adopted in the enzymolysis agent, and its addition is advisable according to the 1-1.3% of slurry weight, and additional amount is advisable according to the 0.3-0.5% of slurry weight.
Described enzymolysis solution filters collection filtrate and is meant that the pH value of adjusting enzymolysis solution is 5-5.5, is warming up to 75 ℃-80 ℃, stirs to add the sodium chloride mixing, is warming up to 90 ℃-95 ℃ again, is incubated 1-2 hour, stops to stir the filtration that warms up, collection filtrate; Treat that filtrate is cooled to 40 ℃-45 ℃, the pH value of adjusting filtrate is 10-11, filters once more, collects filtrate and adjust its pH value to be 8-8.5, and is stand-by.In this step diluted acid and diluted alkaline such as dilute hydrochloric acid and diluted sodium hydroxide solution are adopted in the adjustment of the acid-base value of enzymolysis solution and filtrate; The addition of sodium chloride is incorporated as suitable according to the 4.5-5% of enzymolysis solution weight; Warm up and filter the nylon net cloth that adopts 60 order apertures; Filter the nylon net cloth that adopts 80 order apertures once more.
Described ion exchange absorption is handled and is meant the above-mentioned filtrate of cooling, removes the oils and fats lamella, is warmed up to 45 ℃-50 ℃ then, and it is resin dedicated that stirring adds heparin absorption down, in order to the effective ingredient in the absorption filtrate, after stirring and adsorbing, leaves standstill filtration.The consumption of new resin is generally filtrate 3.5-4%, and stirring and adsorbing was handled 7-8 hour.
The washing of described resin and eluting are meant that to be adsorbed with the heparin absorption of heparin compositions with water rinse resin dedicated, and filter is done; Times salinity of reuse resin volume 0.8-0.85 is the washing of 4.5-5 baume sodium chloride solution, and filter is done; Times salinity that continues with resin volume 0.5-0.6 is a 23-24 baume sodium chloride solution, and adds sodium chloride, and addition is 0.8-1 with the amount of resin ratio: 7.5; Then the heparin that washs is adsorbed resin dedicated employing sodium chloride concentrated solution and carry out the eluting operation as eluent; After eluting finished, the filter dried resin was merged eluent, and filtered with 80 order aperture nylon net cloths, collected eluent.
The operation of described eluting is meant that the eluent salinity is the 18-20 baume, when temperature is 30-35 ℃, for the first time with the 0.8-0.85 eluent eluting doubly of resin volume 3-3.5 hour, for the second time with the 0.5-0.6 eluent eluting doubly of resin volume 3-3.5 hour.
Described clarification filtration is meant that the pH value of adjusting eluent is 11-12, after stirring, leaves standstill clarification, take out the supernatant, the bottom precipitation is carried out sucking filtration, merge clear liquid and filtrate, the adjusting pH value is 5-5.5, adds 3-3.5 80-85% ethanol clarifier doubly, leaves standstill till the clarification of upper strata liquid; Aspirate out the supernatant, collecting precipitation thing and sucking filtration are to doing.
Described drying is meant and places buchner funnel to drain sucking filtration to the heparin sodium precipitate of doing, and puts into exsiccator then, regularly replaces desiccant such as phosphorus pentoxide till no longer absorbing water, and smashs into graininess to pieces, promptly gets heparin sodium crude.
The heparin that contains among the known animal organ is by hexanal acid, iduronic acid, the how sticking sugar that glucuronic acid and the group alternate group that contains the hexylamine sugar of sulfonic acid are made into, can think the mixture of polymer analog and polymer homologue, molecular weight is usually at 6000-20000, can become anion by enzymolysis under certain condition, the reuse resin anion (R.A.) extracts, therefore the present invention is on extracting method, adopt enzymolysis, resin is purified, and facts have proved that the heparin sodium color and luster that the present invention produces is whiter, stable yield, average each pig pulmonis Bovis seu Bubali can extract 0.8-1.2 gram heparin sodium, product quality is also better, on average tires all between 90-120, compares with traditional salt solution, product is tired and can be improved 15%-20%, and productive rate improves more than 10%; The present invention adopts pig, pulmonis Bovis seu Bubali cheap and that be easy to get on raw material, cost is reduced widely, is fit to large-scale production; In the preparation process of the present invention, no toxic and harmful produces, though a small amount of waste residue and small amount of acid alkali cleaning water generates are arranged, waste residue can be processed into feedstuff and sell after drying, and discharging was again compared with the salt solution after acidic and alkaline waste water can neutralize, and had reduced environmental pollution.
The invention will be further described below in conjunction with embodiment:
