PROBLEM TO BE SOLVED: To provide a method for producing a placental extract by which complicatedness of treatment such as regulation of proper action pH in an enzyme digesting process in a conventional method for extraction, removal of hydrochloric acid after completing digestion and final correction of the pH as the placental extract is eliminated. SOLUTION: The complicatedness in an enzyme digesting process, i.e. the complicatedness of the treatment such as the regulation of the proper action pH in the enzyme digesting process, removal of the hydrochloric acid after completing the digestion and final correction of the pH as the placental extract can be simplified by using a specific thermostable neutral proteolytic enzyme. Thereby, effective digestion can be carried out. COPYRIGHT: (C)2004,JPO
