Zusammenfassung:	Highly purified sodium hyaluronate having a low content of pyrogen is obtained by adding a salt and a water-soluble organic solvent to a solution containing sodium hyaluronate, or to a sodium hyaluronate solution previously filtered through a positively charged filter, precipitating and sedimenting the sodium hyaluronate and taking out a supernatant to remove pyrogen.
