Abstract
The invention relates to a method of purifying hyaluronic acid, which comprises the steps of: (a) providing a mixture containing hyaluronic acid; (b) adding active carbon into the mixture in step (a) and allowing active carbon to react with the mixture efficiently; (c) adjusting the pH value of the mixture in step (b) to 2 to 4; (d) passing the mixture in step (c) through a sieve to allow the active carbon to form a cake and passing hyaluronic acid through the cake to obtain the flow-through solution containing hyaluronic acid; and (e) removing the residual active carbon in the flow-through solution and purifing hyaluronic acid from the flow-through solution.
