Embodiment 1

[0056] Experiment A: Extraction of Poria cocos polysaccharide

[0057] Rough extraction method Pulverize Poria with a pulverizer until it can pass through a 60-mesh sieve. Take a total of 15g of Poria cocos powder and dissolve it in 3000ml of 0.5mol / L NaOH solution at 3°C. Add the tetrafluoroethylene rotor and stir in a magnetic stirrer until the powder is completely dissolved, and the solution is viscous at this time. Store in refrigerator at 4°C overnight. Suction filtration the next day, discard the residue and retain the liquid. The filtrate is neutralized with 10% acetic acid solution until its pH is measured between 6-7 with a wide pH test paper. An equal amount of 95% ethanol was added and left overnight at 3°C. Suction filtration the next day to obtain the precipitate. Then, after dialysis with running water for 2 days, it was washed successively with 900ml of distilled water, 300ml of absolute ethanol, 300ml of acetone, and 200ml of diethyl ether. Afterwards, pu...

Description

technical field [0001] The invention relates to a pharmaceutical composition suitable for mild senile vascular dementia. Background technique [0002] Many countries and regions in the world today have entered an aging society. According to foreign statistics, among the elderly over 65 years old, 2-5% are obviously demented, and those over 80 years old account for 15-20%. If combined with light and moderate, it is estimated that the above-mentioned figures will exceed 2-3% times as much. Senile dementia mainly includes two types: Senile Dementia of the Alzheimer type (SDAT) and vascular dementia (Vascular Dementia, VD). Both can exist alone or in combination. Alzheimer type is more common in western countries. According to western statistics, it accounts for about 65% of senile dementia and currently accounts for the fourth cause of death. Vascular dementia is mainly caused by pathological processes such as multiple cerebral infarction, lacunar infarction, single infarct...
