ものは、コスト高になる。Conventionally, hyaluronic acid has been produced by extraction from animal tissues, such as chicken combs on an industrial scale, but it has a low molecular weight due to contaminants such as chondroitin sulfate and hyaluronidase contained in the tissue. Therefore, polymers that are highly purified are expensive.

待たれていた。All conventional m-extension treatment methods, including this method using alumina, involve purifying ζ-aluronic acid in the form of an aqueous solution. When such methods are used, pyrogenic substances, proteins, etc. are not sufficiently removed due to differences in raw materials, and stable effects cannot be obtained in many cases. Therefore, the development of a method to reproducibly and stably obtain high-quality products that can be used as pharmaceuticals has been awaited.

られる事を見出し、本発明を完成するに到った。As a result of extensive research into a purification method that efficiently and reproducibly removes impurities such as proteins, nucleic acids, and metals, resulting in high purity and resistant to lower molecular weight during the construction process, we have purified hyaluronic acid. In this process, they discovered that by performing some or all of the steps using an organic solvent that is miscible with water, impurities such as pyrogenic substances can be stably removed and the objective can be achieved, and the present invention has been completed. reached.
