PROCESS FOR THE PREPARATION OF GASTROINTESTINAL HORMONE

摘要

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 extracted from the small intestine with ethanol, dilute hydrochloric acid or the like. According to this process, however, the efficiency of the extraction 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.
