Embodiment 1
[0027] (1) Weigh 40 g of raw ginseng silk that has been crushed to 20 mesh, put it into a 1000 mL three-neck flask with a solid-to-liquid ratio of 1:30, add ethanol with a mass percentage concentration of 70%, control the extraction temperature at 80°C, and microwave power Under 400 W, ethanol was refluxed for 25 min for primary extraction, filtered to obtain primary ethanol extract, and the filter residue was used for secondary extraction; the solid-liquid ratio of secondary extraction was 1:30, and the extraction time was 25 min at the same temperature, filtered After the dregs, the secondary ethanol extract is obtained, which is combined to obtain the ethanol extract;
[0028] (2) Cool the ethanol extract obtained in step (1) to room temperature and let stand for 3 days, then filter to obtain precipitate A and ethanol extraction filtrate A;
[0029] (3) After the dregs obtained in step (1) are evaporated to remove the solvent, add distilled water and put it into a microwave...
Embodiment 2
[0035] (1) Weigh 30 g of ginseng rhizome raw material crushed to 40 mesh, put it into a 1000 mL three-neck flask, the solid-liquid ratio is 1:20, add ethanol with a mass percentage concentration of 75%, put it into a microwave extractor, and control the extraction Temperature 60 ℃, microwave power 600W, reflux extraction for 20 min for primary extraction, filtration to obtain primary ethanol extract, and filter residue for secondary extraction. The solid-liquid ratio of the secondary extraction was 1:20, and the extraction time was still 20 min at the same temperature. After filtering the dregs, the secondary ethanol extract was obtained, and the ethanol extract was combined;
[0036] (2) Cool the ethanol extract obtained in step (1) to room temperature and let stand for 4 days, then filter to obtain precipitate A and ethanol extraction filtrate A;
[0037] (3) After removing the solvent from the medicinal residue obtained in step (1), add distilled water and put it into a mic...
Embodiment 3
[0044] (1) Weigh 40 g of ginseng rhizome raw material crushed to 60 mesh, put it into a 1000 mL three-necked flask, add ethanol with a mass percentage concentration of 85% at a solid-to-liquid ratio of 1:15, and put it into a microwave extractor to control The extraction temperature was 70°C, the microwave power was 700W, and the reflux extraction was performed for 10 min for the first extraction, and the first ethanol extract was obtained by filtration, and the filter residue was used for the second extraction. Add ethanol with a mass percentage concentration of 85% for the secondary extraction, the solid-liquid ratio of the secondary extraction is 1:15, and the extraction time is still 10 min at the same temperature. After filtering the dregs, the secondary ethanol extract is obtained, and combined ethanol extract;
[0045] (2) Cool the ethanol extract obtained in step (1) to room temperature and let stand for 4 days, then filter to obtain precipitate A and ethanol extractio...
