[Detailed Description of the Invention] The present invention relates to acidic mucopolysaccharide (hereinafter referred to as AMPS)
Regarding preparative methods. In detail, when obtaining AMPS from chicken combs, we will introduce a method for selectively and equivalently eluating hyaluronic acid (hereinafter referred to as HA), which has properties close to its natural state, by treating raw chicken combs with protease. Furthermore, chondroitin sulfate (hereinafter referred to as CHS) remaining in the comb from which HA has been eluted is fractionally eluted by treatment with a salt solution, and then acid-soluble collagen (hereinafter referred to as CL) is extracted from the residue. )
Concerning extracting. HA is a type of AMPS that is widely present in the connective tissue of animals, and is a chain-like macromolecule with repeating units of N-acetyl hyalobiuronic acid. Its aqueous solution exhibits strong water retention and viscoelasticity, and is bioactive. It is known that they play important functions in the body, such as controlling the movement of substances between cells, defending against bacterial invasion, and controlling cell proliferation and differentiation. HA is also used for medical purposes in the field of ophthalmology (retinal detachment) (Mod. Probl. Ophthal., 12,
370-377, 1974), for the joint area (arthritis) (Acta Vet.Scand., 17 , 379-394, 1976), for the skin area (dermatitis) (Osped.Ital.Chir.,
19 , 173-188, 1968), and their therapeutic effects have been recognized, but in all cases, polymers are considered desirable. CHS is generally classified into three isomers: CHS-A, -B, and -C. Of these, CHS-A and -C exist in large amounts in cartilage, while CHS-B is found in cartilage. It is known that it is almost absent, but exists in the skin, tendons, aorta, etc. It has also been reported that its physiological activity plays a certain role in tissue fibrosis (Biochem, J, 109 , 857-867,
(1968), which is indispensable for research on mucopolysaccharides.

Now, cockscomb is made of high molecular weight hyaluronan and most of it is CHS-
It is very different from other connective tissues in that it contains CHS (B) and almost no other AMPS. Known methods for producing HA from chicken combs include mincing chicken combs, defatting and denaturing them with an organic solvent such as acetone, and then extracting with a large amount of water or a salt solution (BBA 156 , 17-30, (1968), minced chicken comb, defatted it with an organic solvent such as acetone, denatured it, and then digested it with protease to elute AMPS (J.
Histochem.Cytochem., 6 , 416-424, 1958)
There are methods for fractionating HA using the following known methods, but in the former, the extraction efficiency of HA is extremely poor and the yield is low, and in the latter, CHS is eluted together with HA, so ammonium sulfate is removed in the presence of pyridine or alcohol. A complicated hyaluronan fractionation operation, typified by fractionation, is required, and hyaluronan is reduced in molecular weight by such fractionation operations. Furthermore, both methods require acetone treatment, but a large amount of acetone is required to treat chicken combs with acetone, which makes them unsuitable as industrial methods.

In addition, column chromatography using ion exchange resin is a common AMPS fractionation method.
This method is industrially impossible because the molecular weight of HA is significantly reduced and the HA in the comb is highly viscous.

Now, the inventor of the present application has discovered that HA, which is AMPS in the cock's comb,
We worked hard to find a method to easily separate CHS, and in the patent application No. 60574, filed earlier, we collected 35 chicken combs.
After heating at ~65℃, protease treatment was performed.
We have described a preparative method for AMPS that involves selectively eluating only hyaluronan as AMPS with properties close to its natural state. However, as a result of further investigation, we found that heating at 35 to 65°C is not necessarily necessary, and that simply treating the comb raw with protease without defatting and denaturing it will bring it closer to its natural state. HA having the properties can be selectively and equivalently eluted, and in this way
The present invention was achieved by discovering that CHS can be fractionated in equivalent amounts by treating chicken comb residue from which hyaluronan has been eluted with a salt solution. In the present invention, "raw" means defatted,
This means that no denaturing treatment is performed, and does not mean that operations such as freezing for preservation are excluded.

It is well known that fresh chicken comb is shredded and treated with protease at pH 5-8 and kept at 35-60°C, and then the liquid phase and residue are separated, and HA is selectively and equivalently eluted into the liquid phase. Cetylpyridinium chloride is added to this according to the method of 2009, the resulting precipitate is dissolved in an aqueous solution containing salt and alcohol, alcohol is further added, and the resulting precipitate is collected and dried to obtain HA. In addition, HA is fractionated, resulting in AMPS.
After treating the comb residue containing only CHS with a neutral salt solution, it is separated into a liquid phase and a residue, and the liquid phase is adsorbed to an anion exchange resin according to a known method and washed to remove contaminant proteins. After removing and eluting with an appropriate salt solution, alcohol is added to the eluate, and the resulting precipitate is collected and dried to obtain CHS.

Using conventionally known proteases
In the HA extraction method, HA and CHS are eluted at the same time because the chicken comb is defatted and denatured, and then treated with protease, which requires complicated operations to separate, and furthermore, HA is inevitably reduced to a lower molecular weight. It had been. However, according to the method of the present invention, the difficulties seen in these conventional methods can be solved, and AMPS, which is a useful component in chicken comb, can be easily and efficiently separated. Note that unlike conventional methods, the method of the present invention hardly denatures CL in the chicken comb, and therefore, the residue of the chicken comb from which AMPS has been separated can be further used as a raw material for the production of acid-soluble CL.

Protease treatment in HA extraction of the present invention is
It is carried out at a temperature of 35 to 60°C at a pH of 5 to 8.
As for the protease used in this case, any neutral protease having an activity between pH 5 and 8 can be used, except for collagenase. Protease treatment in a PH range exceeding PH8 is not preferable because it leads to lower molecular weight of hyaluronan and contamination with CHS.
In a PH range of less than 5, the extract becomes viscous, making subsequent operations complicated, and elution of collagen occurs, which is undesirable. In addition, protease treatment at temperatures exceeding 60°C is undesirable as CHS co-elutes.
Protease treatment at temperatures below 35°C is not practical, as the elution of hyaluronan is delayed considerably, requiring a long time. The protease treatment time is determined by the type of enzyme, the amount of oxygen, and the treatment temperature.

Salts in the salt solution in salt solution treatment of HA extraction residue include sodium chloride, lithium chloride, potassium chloride, ammonium chloride, barium chloride, magnesium chloride, calcium chloride, manganese chloride, zinc chloride, iron chloride, aluminum chloride, sodium sulfate, Organic salts and inorganic salts such as potassium sulfate, magnesium sulfate, calcium sulfate, ammonium sulfate, sodium nitrate, potassium nitrate, ammonium nitrate, calcium nitrate, magnesium nitrate, sodium acetate, ammonium acetate, magnesium acetate, and other neutral salts. You can use any of them if you have them. Industrially, sodium chloride, magnesium chloride, ammonium sulfate, etc. are preferred because they are inexpensive and easy to process. As the concentration of salt solution
Approximately 0.02 to 1.0M is preferable. If the salt concentration is lower than the above, the extraction time must be significantly extended, and if it is higher than the above, the removal of salt from the extract becomes complicated. There is no particular limit to the pH of the salt solution, but
In order to prevent denaturation of the extraction residue, it is preferable to maintain the pH between 5 and 8.

For example, by separating proteins using an anion exchange resin, eluting with a salt solution, adding alcohol, separating the resulting precipitate, and drying it, it is easy to obtain highly pure proteins.
