Embodiment 1

[0038] The preparation of embodiment 1 alpine edelweiss extract

[0039] Accurately weigh 1000g of alpine edelweiss fresh grass, crush and preform into powder, add 2000mL of 95% ethanol at a material-to-liquid ratio of 1:2 (m / v), stir and mix, and ultrasonically treat for 15min (ultrasonic power: 300w, ultrasonic temperature: 25°C). Add 8 L of pure water 8 times the cell mass to the edelweiss solution treated by ultrasonic wall breaking, extract at a high temperature of 100°C for 1 hour, and then centrifuge at 6000g for 10 minutes, and the obtained supernatant is liquid A.

[0040] Accurately weigh 1000g of alpine edelweiss hay powder, add 10000mL of 95% ethanol in batches at a material-to-liquid ratio of 1:10 (m / v) for Soxhlet extraction until colorless, and centrifuge at 6000g for 10 minutes to collect the extract as liquid B.

[0041] Take 3L of liquid A and 3L of liquid B, mix them evenly, concentrate under reduced pressure and freeze-dry to obtain the extract C of edelwe...

Abstract

The invention provides a pharmaceutical composition for intervention of mild cognitive impairment. The pharmaceutical composition is composed of NMN, a leontopodium alpinum extract and a pharmaceutically acceptable auxiliary material. The leontopodium alpinum extract can significantly reduce the drug concentration of the NMN in intervention of mild cognitive impairment.

Description

technical field [0001] The invention belongs to the technical field of medicines. Specifically, the invention provides a brain-invigorating drug composition containing NMN, which is used for inhibiting mild cognitive impairment caused by oxidative stress. Background technique [0002] Mild cognitive impairment (Mild congnitive impairment, MCI) refers to a transitional stage of cognitive impairment between normal aging and Alzheimer's disease (AD) at the same age and education level. Avoid oxidative stress (Oxidative Stress, OS) damage. Therefore, the body's antioxidant therapy has become the main clinical means to prevent and inhibit MCI. [0003] However, after it was found that the use of conventional antioxidants such as vitamin C, vitamin E and β-carotene had little effect on improving the damage caused by oxidative stress, it began to turn to natural antioxidants such as resveratrol, stilbene glycosides, etc. Although the extraction, function, and mechanism research o...
