Abstract
The invention relates to a chondroitin sulfate sodium extracting method. Chondroitin sulfate sodium is a mucopolysaccharide substance extracted from animal cartilages, such as hog snout cartilages. A traditional process method adopts alkaline hydrolysis, enzyme hydrolysis, slat hydrolysis and ion exchange resin or their combinations to perform extraction, an extracting solution still contains a large amount of protein, nucleic acid and other impurities, and a certain problem is brought to further purification. The chondroitin sulfate sodium extracting method adopts an alkaline hydrolysis-enzyme hydrolysis method and a flocculation precipitation method to remove the impurities left in the chondroitin sulfate extracting solution, is reasonable in process design and high in removing efficiency, the follow-up refine work time is shortened, the product yield is improved, and the method conforms to the standards of Chinese Pharmacopoeia of 2010 edition.
Description
Technical field
Field belonging to the present invention is biochemical pharmacy field, relates to a kind of extracting method of Sodium chondroitin sulfate A, particularly a kind of Sodium chondroitin sulfate A producing and manufacturing technique.
Background technology
Sodium chondroitin sulfate A is a kind of acid mucopolysaccharides extracting preparation from animal cartilaginous tissue, belongs to glycosaminoglycan.Clinically be mainly used in lipid regulating agent, sacroiliitis, eye drop etc.Sodium chondroitin sulfate A is a kind of biochemical drug of outbalance in the market, is recorded in " Chinese Pharmacopoeia (2010 editions) ".In recent years, the trend that Sodium chondroitin sulfate A is consumed as healthcare products heats up gradually, makes its Application Areas more and more extensive.
Traditional process for extracting takes the method for alkaline hydrolysis, enzymolysis, salt solution and ion exchange resin or its combination to extract, extraction efficiency is low, complex operation, still containing the impurity such as a large amount of protein and nucleic acid in extracting solution, brings certain difficult problem to being further purified.
Summary of the invention
Object of the present invention provides a kind of method extracting Sodium chondroitin sulfate A, namely alkaline hydrolysis-enzymolysis process is in conjunction with flocculent precipitation, can effectively remove impurity remaining in extracting solution, effective simplification refining step, save ethanol consumption in settling step, the Sodium chondroitin sulfate A product that foreign matter content is low, yield is good can be produced in the shorter time.
Object of the present invention reaches by the following technical programs, is realized successively by following step.
(1) cartilage soaks: hog snout diaphyseal bone joined with the complete submergence of water in retort, soak after 3-5 hour, puts dry immersion water;
(2) alkaline hydrolysis: add alkali lye, the ratio of dry bone weight and alkali lye weight is 1:2-1:3, stirs and extracts after 3-5 hour, with 100 order nylon net filters;
(3) enzymolysis: after regulating pH8-9, be warming up to 45 DEG C, add pig source pancreatin and sodium-chlor, 45-50 DEG C of insulation 3-5 hour;
(4) rise suddenly temperature: be warming up to 80-85 DEG C, leaves standstill 15-20min, with sock filtration;
(5) ratio of 20%-30% adds 95% ethanol in filtered liquid by volume;
(6) flocculating settling: control temperature 40-50 DEG C, regulates pH11-12, adds flocculating settling agent in 0.3%-0.5% (mass/volume) ratio, and leave standstill until layering, siphon supernatant, the centrifugal rear merging mother liquor of throw out, in supernatant liquor, discards centrifugal slag;
(7) after desolventing technology, alcohol settling, dewatered drying, obtains the Sodium chondroitin sulfate A of separation and purification.
The beneficial effect of the technical program is: through alkaline hydrolysis-enzymolysis process in conjunction with the obtained Sodium chondroitin sulfate A of flocculent precipitation, content more than 90%, yield >=30%.
(1) in the technical program, enzymolysis step adds sodium-chlor in (3), and the weight ratio of its weight and dry bone is 3%-5%.Can hydrolysis result be strengthened, Sodium chondroitin sulfate A is effectively separated with impurity such as albumen.
(2) in the technical program, in alkaline hydrolysis step (2), the concentration of alkali lye used is 1-2mol/L, can reduce the destruction of alkali lye to Sodium chondroitin sulfate A, improves yield.
(3) in the technical program, the pig source pancreatin weight added in enzymolysis step (3) and the weight ratio of dry bone are 1%-2%, and soaking time is 3-5 hour, can reduce the destruction of pancreatin to Sodium chondroitin sulfate A, improve yield.
(4) in the technical program, add ethanol in flocculating settling forward direction filtrate, this alcohol concn is 95%, and is 20%-30% with filtering the volume ratio at night.The combination of the impurity such as protein nucleic acid and flocculating settling agent can be increased like this, increase granularity, contribute to sedimentation.
(5) in the technical program, flocculating settling agent is selected from hydroxyapatite (HAP) and sodium laurylsulfonate (SDBS) or its mixture, can the effective impurity such as associated proteins nucleic acid form throw out, removes after centrifugal.
Embodiment
Following instance describes the present invention in detail:
