Abstract:
Provided are an anti-Alzheimer′s pharmaceutical composition and a functional health food for alleviating Alzheimer′s, wherein a water-soluble monomer derived from a hot water extract of a Phellinus linteus fruit body is contained as an active ingredient. The pharmaceutical composition and functional health food according to the present invention inhibit the activity of beta secretase related to the production and accumulation of beta amyloid peptides which are considered to be the cause of Alzheimer′s. Accordingly, the pharmaceutical composition containing water-soluble polysaccharides can be utilized as a medical product or a functional health food for preventing or treating Alzheimer′s.
