GLYCOPROTEIN AND APPETITE INHIBITOR COMPRISING THE SAME AS ACTIVE INGREDIENT

摘要

PURPOSE:To obtain a new glycoprotein separated from a fruit body of Pleurotus ostreatus and an appetite inhibitor comprising the glycoprotein an active ingredient. CONSTITUTION:This glycoprotein is separated from a fruit body of Pleurotus ostreatus and has the following properties (1) to (5): (1) Number-average molecular weight (get filtration, calculated as dextran): 70,000-90,000. (2) Isoelectric point: 8.2-9.2. (3) Saccharide content (phenol-sulfuric acid method): 2.2-3.0wt.%. (4) N-End amino acid sequence: alanine-threonine-valine-lysine-isoleucine- threonine-alanine-threonine-proline-arginine-glutamine-phenylalanine-g lycine. (5) Lectin activity: exists.
