Description
Technical field
The present invention relates to biochemical pharmacy field, in particular to a kind of preparation method of heparin lithium.
Background technique
Heparin is mainly extracted from intestinal mucosa, is one kind by gucosamine, L- idose aldehyde glycosides, N-Acetyl-D-glucosamine
The glutinous Alginic Sodium Diester alternately formed with D-Glucose aldehydic acid.Heparin is a kind of natural anticoagulative substance, by with anticoagulation
Enzyme III, which is combined, makes it expose arginine reaction center, its inactivation is made in conjunction with the coagulation factor of activation, main to inactivate Xa and IIa
The factor.Heparin is mainly used for preventing and treating thrombotic disease, as myocardial infarction, pulmonary embolism, cerebral vessels embolism, periphery are quiet
Arteries and veins thrombus etc., can anti-tampon formation and expansion.Can also be used in DIC early stage and other inside and outsides it is anticoagulant.
Heparin lithium has better anticoagulating active than heparin sodium, has unique value in clinical examination, is widely used in urgency
Examine biochemical analysis, the acquisition of blood preparation of lectin from hemolymph inspection and anticoagulant.Serum is precipitated since blood is retracted to solidification from human body
The time for generally requiring one hour or more seriously affects emergency treatment result report time, therefore clinical emergency often uses heparin anti-coagulating
Slurry carries out biochemical analysis.When examining the sodium ion in blood specimen, to avoid influencing testing result, commonly uses heparin lithium and replace.This
Outside, heparin lithium or the ideal anti-coagulants of erythrocyte infiltration test.
Currently, the preparation of heparin lithium is prepared as raw material, by sodium ion with exchanging for lithium ion using heparin sodium, ion
Heparin lithium solution after exchange generallys use freeze-drying or intermediate processing obtains product.And desivac is at high cost and is unsuitable for scale life
It produces.Since lithium ion molecular weight is small in the precipitation method, density, viscosity are small, and heparin lithium is assembled when organic solvent is added in heparin lithium solution
Settling velocity is slower, and needs to be added the organic solvent compared with high magnification numbe, and impurity is easy Precipitation, therefore influences product quality,
And heparin lithium molecular weight, in 3000 ~ 50000 dalton, the heparin lithium aggregate and precipitate of each segment molecule amount is inconsistent.Simultaneously precipitating by
In having viscosity, causes precipitating to be easy to stick at production equipment inner wall, influence production efficiency.
Summary of the invention
Goal of the invention: aiming at the problems existing in the prior art, the present invention provides a kind of preparation method of heparin lithium, it is intended to
The preparation cost for reducing heparin lithium promotes the quality and yield of product, improves production efficiency.

Organic solvent.
Preferably, the organic solvent be it is following any one or combinations thereof: ethyl alcohol, methanol, acetone, isopropanol.
The utility model has the advantages that the advantages of present invention has compared with prior art are as follows: the present invention is using heparin sodium as raw material, under low temperature
Be converted to heparin lithium by ion exchange, the heparin lithium concentrate obtained by ultrafiltration, control appropriate solution concentration, temperature and
Under ionic strength conditions, organic solvent, which is added, using compartment in batches makes the heparin lithium of different molecular weight section be in colloidal precipitation,
The higher heparin lithium of molecular weight is initially formed colloidal precipitation.Dispersion should be avoided to have been formed as far as possible when organic solvent is added in stirring
Heparin lithium colloid, gained heparin lithium product purity is high, quality is stablized, at low cost;Preparation method of the invention forms heparin lithium
Colloidal precipitation is gathered in device bottom in fluid state, avoids the viscous glutinous equipment inner wall of product, improves production efficiency.Process conditions
