    摘要: A partially purified product of a hyaluronic acid salt obtained from a culture of a microorganism capable of producing hyaluronic acid, preferably a microorganism belonging to the genus Streptcoccus, is brought into contact with a solution containing a salt and a hydrophilic organic solvent, thereby transferring to a liquid phase, impurities contained in said partially purified product such as proteins, nucleic acids, colorants, endotoxins and the like, and then isolating the hyaluronic acid salt as a precipitate.

    摘要: Present invention relates to a method for preparing low molecular weight hyaluronic acid and the salt thereof from high molecular weight hyaluronic acid using by ion exchange resin and it has various advantages over prior arts such as easy to mass production, economic production, uniform production of purposed low molecular weight hyaluronic acid, prevention of the ring cleavage of monosacchride in hyaluronic acid occurring in chemical hydrolysis and undesired formation of by-product having double bonded sugar ring occurring in enzymatic hydrolysis. Therefore, the inventive method of the present invention could provide effective and economic method for preparing low-molecular weight hyaluronic acid with mass production and low cost and the low molecular weight hyaluronic acid and the salt thereof prepared from the method of the present invention may extensively be used as a medicine, cosmetic, medical material, food additives etc.
