Abstract
It is to provide a method for producing hyaluronic acid or a hyaluronic acid derivative which is a simple preparation method as compared with a cockscomb extraction method or a fermentation method which has conventionally been employed industrially, and with which isolation and purification of the product from the reaction liquid is easy. It is a method for producing hyaluronic acid or a hyaluronic acid derivative, which comprises acting a hyaluronidase on an oxazoline derivative.
