Abstract:
PURPOSE: A pharmaceutical composition for preventing or treating dementia is provided to suppress the activity of acetylcholine esterase, to effectively prevent and treat dementia, and to produce a pharmaceutical composition and a health food. CONSTITUTION: An inhibitor of acetylcholine esterase activation contains a compound of chemical formula 1 or a pharmaceutically acceptable salt thereof as an active ingredient. The compounds are derived from Hericium erinacium. A method for manufacturing the inhibitor comprises the steps of: pulverizing Hericium erinacium; adding alcohols to the pulverized Hericium erinacium and concentrating the extract by reduced pressure; preparing a primary fraction from the concentrated extract using an organic solvent; preparing a secondary fraction from the primary fraction through chromatography; and isolating and purifying the compound of chemical formula 1.
