specific Embodiment 1
[0049] Soak Epimedium in ethanol, extract, and extract the dregs with water, as component 1;
[0050] Extraction and preparation of other raw materials as component 2;
[0051] Combine components 1 and 2, concentrate, add dextrin or honey to blend, sterilize with ultraviolet rays, and bottle.
specific Embodiment 2
[0052] Put 5000g of Epimedium into ethanol which accounts for 10 times its mass, heat and reflux to extract twice, each time for 1-2 hours, remove the supernatant, combine the extracts, filter at 100-110 mesh, and then pass through the cut-off molecular weight Ultrafiltration with an ultrafiltration column of 6000-10000, the ultrafiltrate is decompressed and concentrated to an extract with a relative density of 1.36 at 80°C, heated and concentrated to a paste, and left standing for later use; Water with 10 times the mass was heated and refluxed twice, the supernatant was removed, the extracts were combined, filtered through 100-110 mesh, and then ultrafiltered through an ultrafiltration column with a cut-off molecular weight of 6000-10000, and the ultrafiltrate was concentrated under reduced pressure. The extract with a density of 1.36 at 80°C is heated and concentrated to a paste, and left to stand for later use; the above two extracts are combined, the ethanol is recovered, a...
specific Embodiment 3
[0055] Soak 4000g of Epimedium in water for 2-5 hours, add 8 times of its mass and 6 times of water to extract twice, and the extraction time is 2 hours and 1 hour; combine the 2 extracts, and the extracts pass through the tube formula centrifugation to obtain a centrifuge, which is adsorbed by D 101 macroporous resin, washed with water to remove impurities, then eluted with 70% ethanol, collected eluate, concentrated under reduced pressure, and becomes an extract, for subsequent use; Add ethanol to the dregs of the above-mentioned extracted Epimedium, add 10 times the amount of its mass, 8 times the amount of ethanol to warm soak twice, the soaking time is 2 hours, 1.5 hours, the temperature is 85 ° C, combined 2 Sub-temperature infusion; the warm infusion is concentrated under reduced pressure to a density of 1.25 at 60°C, and the extract is extracted twice by adding 4 times the amount of ethyl acetate, and the extract is recovered from the ethyl acetate to form an extract fo...
