Description
Technical field
The present invention relates to technical field of heparin sodium production, particularly a kind of using alkali proteinase method extracts the technique of heparin sodium from intestinal mucosa.
Background technology
Heparin sodium, also known as heparin, is a kind of natural anticoagulative substance of acid mucopolysaccharides containing sulfate.Heparin sodium is white or off-white powder, and odorless, tasteless has and draws moist, soluble in water, is insoluble to the organic solvents such as ethanol, acetone, dioxane.
Heparin sodium is extensively present in Mammals liver, lung, intestinal mucosa, how to become complex body to exist with protein bound.The separable heparin sodium of enzymolysis protein, heparin sodium is the mucopolysaccharide of sulfur acid, amino, glyconic acid.When pH8-9, electronegative, ion-exchange can be carried out with anionite, carry out roughing out, polysaccharide liquid precipitate in high concentration ethanol carry out consummate.Heparin sodium is antithrombotics best during blood chemistry measures.Heparin sodium is a kind of mucopolysaccharide of sulfur acid group, molecular weight is 1.5 ten thousand, and its anticoagulant mechanism is together with anti-freezing enzyme II, in lower concentration energy supressor Ⅸ a, effect between VIII and PF3, and antithrombin Ⅲ deactivation serine protease can be strengthened, thus zymoplasm is stoped to be formed; Also have the self-catalysis of Trombin inhibiting and the effect of supressor X.
The defect of the enzymolysis production method of traditional heparin sodium is: the production cycle is long, and energy consumption is large, and yield is low, produce 100,000,000 international unit heparin sodium crudes and need 2800-3000 root chitterlings, product purity is low, and tiring of heparin sodium is at most 80U/mg, and produce a large amount of intestines slags and waste water, contaminate environment.A kind of method utilizing bio-fermentation process to produce heparin sodium of the disclosure of the invention of CN1308088A.The method adopts 2709 proteolytic enzyme as catalyzer, and D204 strongly basic anion exchange resin as ion exchange resin, and adopts 150-180 order multilayer cloth screen to filter.The defect that the method exists is: product yield, purity are also lower, and produce a large amount of intestines slags and waste water, contaminate environment.
Summary of the invention
The object of the invention is to the above-mentioned defect overcoming prior art existence, provide a kind of using alkali proteinase method to extract the technique of heparin sodium from intestinal mucosa, with short production cycle, product yield, purity are high, decrease the discharge of intestines slag and waste water, are beneficial to environmental protection.
The technical solution adopted for the present invention to solve the technical problems is:
Using alkali proteinase method extracts a technique for heparin sodium from intestinal mucosa, and described processing step is as follows:

2. using alkali proteinase method according to claim 1 extracts the technique of heparin sodium from intestinal mucosa, it is characterized in that: re-use after the resin activated process of described ROHM AND HAAS FPA98CL type, activation treatment is: resin 50-60 DEG C warm water soaking is rinsed well with clear water after more than 20 hours and drained, add again mass concentration be 10% sodium hydroxide solution stir more than 1 hour, it is neutral for finally rinsing to washing lotion pH with clear water, and the add-on of described sodium hydroxide solution is the gauge that every kilogram resin adds 1L sodium hydroxide solution; Resin after activation is under the rotating speed of 4000-5000 rev/min, and centrifugal treating 10-30min, is used further to absorption.
3. using alkali proteinase method according to claim 1 extracts the technique of heparin sodium from intestinal mucosa, it is characterized in that: enter step (5) precipitation after the elutriant that step (4) is collected enters ultrafilter ultrafiltration again, the ultra-filtration membrane aperture of ultrafilter is at 0.45 μm-0.6 μm.
4. using alkali proteinase method according to claim 1 extracts the technique of heparin sodium from intestinal mucosa, it is characterized in that: the elutriant that step (4) is collected, under the rotating speed of 8000-10000 rev/min, after centrifugal treating 10-20min, then enters step (5) precipitation.
5. using alkali proteinase method according to claim 1 extracts the technique of heparin sodium from intestinal mucosa, it is characterized in that: the temperature of step (6) drying and processing is 60-80 DEG C.
