[0114] Preparation of Astragalus Polysaccharide: Take 2Kg of Radix Astragali, extract twice at 70°C with 10 times the amount of water, for 2 hours each time. Collect the extract, concentrate it to about 1L, place it at room temperature, centrifuge, add pre-cooled ethanol to the supernatant to make the alcohol content reach 65%, let it stand at 4°C for 24 hours, and take the precipitated astragalus crude polysaccharide. Dissolve Astragalus crude polysaccharide in 500 mL of water, add an equal volume of 5% trichloroacetic acid, shake at 5°C for 10 minutes, stand at 5°C for 1 hour, centrifuge to remove precipitate, and treat in the same way 3 times to remove protein. Adjust the pH value of the polysaccharide solution after protein removal to 7.0 with NaOH, centrifuge, add pre-cooled ethanol to the supernatant to make the alcohol content reach 75%, let it stand at 4°C for 24 hours, and take the precipitated astragalus polysaccharide. Astragalus polysaccharide was dissolved in 25L ...
