A
drug compound preparation for treating Alzheimer's
disease includes the main components of
epigallocatechin gallate and
vitamin E. Oil-soluble
vitamin E is mixed with 1 part by volume of
edible oil solution, and water-soluble EGCG is mixed with 2 parts by volume of
distilled water; the two liquids are mixed and then added with an emulsifier in the weigh 10% of the
edible oil, so as to form an oil-water suspension with
mass fraction of EGCG of 0.02-0.1% and
mass fraction of
vitamin E of 0.3%. The invention has the
advantage that the
drug compound preparation has significant improvement on learning and
memory impairment in an Alzheimer's
disease mouse model induced by D-
galactose, and can reduce the deposition of A beat 1-40 in the brain; and the
drug compound preparation reduces antioxidation stress effect, anti-
apoptosis effect and anti-inflammatory effect by increasing
antioxidant enzymes, so as to exert the effect in resisting Alzheimer's
disease. The
drug compound preparation has simple composition, clear
efficacy and easy preparation, can effectively play the roles of improving the behavior and learning and
memory functions of patients, and does not generate other adverse reactions in
large dose application.
