    • PURPOSE: A method for extracting hyaluronic acid from rooster combs is provided, to obtain the highly pure hyaluronic acid by controlling the ionic strength of the salt added to a solution and simplifying the process. CONSTITUTION: The method comprises the steps of extracting the pulverized rooster combs with a solvent mixture of distilled water and chloroform, and filtering it to obtain a rooster comb solution; adding a salt solution to the rooster comb solution and stirring it; adding chloroform to the obtained solution and stirring it to obtain a first supernatant; centrifuging the first supernatant to obtain a second supernatant; and adding ethanol to the second supernatant and leaving it alone to obtain the precipitated hyaluronic acid. Preferably the ratio of distilled water and chloroform in the solvent mixture is 20:1 by volume; and the final concentration of salt is 0.3-4 M after the salt solution is added to the rooster comb solution.
    • 目的:提供从雄鸡梳中提取透明质酸的方法,通过控制添加到溶液中的盐的离子强度和简化方法获得高纯度透明质酸。 构成:该方法包括用蒸馏水和氯仿的溶剂混合物提取粉碎的雄鸡梳子,并过滤以获得公鸡梳子; 向公鸡梳中加入盐溶液搅拌; 向所得溶液中加入氯仿并搅拌,得到第一上清液; 离心第一上清液以获得第二上清液; 并向第二上清液中加入乙醇,并将其单独留下以获得沉淀的透明质酸。 溶剂混合物中蒸馏水和氯仿的比例优选为20:1体积比; 在盐溶液加入到公鸡溶液中之后,盐的终浓度为0.3-4M。
