Abstract

The invention concerns a method of producing breakdown products of polymer glycosaminoglycans, an aqueous solution of one or a plurality of polymer glycosaminoglycans being prepared and the solution being subjected to an ultrasound treatment. Preferably, heparin, chondroitin sulphate, dermatan sulphate, keratan sulphate, hyaluronic acid, mesoglycan and/or alginic acid are used as polymer glycosaminoglycan.
