Abstract
Gastric acid secretion inhibiting substance obtainable from mammalian urine by conventional method is fractionated into the first and second components by gel filtration, adsorption and desorption on ion exchanger or electrophoresis detecting each component by biological test methods. The activities of the two components differ from each other in the biological tests. The first component is a glucoprotein-like substance of M.W. 100,000 and the second component is a peptide-like substance of M.W. about 6,000.
