Examples
Embodiment 1
[0065] Example 1 Preparation of Astragalus Powder
[0066] The astragalus root with high medicinal value is selected for preparation, the harvested astragalus root soil is washed and sliced, and the length of the cut is 0.3-0.5cm. The astragalus slices are dried in a drying box, and the drying temperature is The drying time is 3h at 90°C, and the dried astragalus slices are fed into the pulverizer in time while they are hot for pulverization, pulverized to 900 mesh, the pulverized astragalus powder is sterilized and packaged in a vacuum.
Embodiment 2
[0067] Example 2 Preparation of Astragalus Extract by Ethanol Extraction Method
[0068] Astragalus root with high medicinal value is selected for preparation, the raw astragalus root is dried, baked at 90℃, pulverized to 20 meshes to obtain astragalus coarse powder, astragalus coarse powder is extracted 3 times with 80% ethanol solution, and the extract is filtered Then it was concentrated under reduced pressure to obtain the astragalus concentrate. The astragalus concentrate was eluted through the adsorption column. The adsorption column packing was HPD100, which was washed with purified water to remove impurities, and then eluted with 60%, 70%, and 80% ethanol. The eluent is concentrated under reduced pressure, decolorized, refined, concentrated under reduced pressure to extract, and freeze-dried to obtain an Astragalus extract.
Embodiment 3
[0069] Example 3 Preparation of Astragalus Extract by Decoction Method
[0070] Astragalus root with high medicinal value is selected for extraction. Weigh 100g of astragalus root, put it in a decoction vessel of suitable volume, add about 600ml of water to immerse the medicinal materials for 1h, boil and heat for 0.5h. Separate the decocted liquid and decoct the medicine residue for a second time. The decocted liquid is mixed with the first decocted liquid, and the volume is measured with a measuring cylinder. If the volume exceeds 600ml, the decocted liquid will be further boiled and concentrated to about 600ml to reach the corresponding volume Afterwards, the decocted liquid is vacuum packaged, put into 7-8 small bags, and stored at 4°C until use.
