ABSTRACT OF THE DISCLOSURE The present invention relates to a process for preparing a gastrointestinal hormone from the small intestine of a mammal at a high yield. As the process for the preparation of gastrointestinal hormone, there has been a well known process in which the hormone is directly ex- tracted from the small intestine with ethanol, dilute hydrochloric acid or the like. According to this process, however, the efficiency of the extrac- tion of gastrointestinal hormone is extremely low, and this process cannot be used as an industrial process. In accordance with the present invention, there is provided a process for the preparation of gastrointestinal hormone characterized by heating the small intestine of a mammal in an aqueous solution of a salt, extracting gastrointestinal hormone and purifying it.
