摘要：

Provided a method of producing a purified hyaluronic acid type which comprises adding a water-soluble organic medium to a solution which comprises a hyaluronic acid type having an average molecular weight of 400 to 100,000 and has a pH of 3 or less to obtain a suspension, and adjusting a pH of the suspension in a range of 3.5 to 8 to precipitate a purified hyaluronic acid type.
