Embodiment 1
[0049] Take the propolis medicinal material, freeze (-10°C-4°C) for 5 hours, crush it into a coarse powder, add 95% ethanol to extract twice at a ratio of 20ml per gram of propolis, each time for 24 hours, filter, combine the filtrate, reduce The solvent was recovered under pressure, concentrated into a thick paste, dried under reduced pressure at 80°C and 0.05Mpa, and crushed into fine powder. Add 100ml of chloroform-ethanol (10:1-3:1) per gram of dry powder to dissolve, extract twice with an equal volume of 5% sodium hydroxide solution, add hydrochloric acid to the alkaline extract to adjust the pH to 4-8, produce precipitation, and let it stand for 24 hour, filter with suction, wash with water until neutral, dry under reduced pressure at 60°C and 0.05Mpa, and pulverize into fine powder to obtain the propolis flavonoid extract of the present invention.
Embodiment 2
[0051] Take the propolis medicinal material, freeze (-10°C-4°C) for 5 hours, crush it into coarse powder, extract twice with 65% ethanol at a ratio of 10ml per gram of propolis, 10 hours each time, filter, combine the filtrates, and recover under reduced pressure The solvent is concentrated into a thick paste, dried under reduced pressure at 55°C and 0.05Mpa, and crushed into fine powder. Add 200ml of chloroform-ethanol (10:1-3:1) per gram of dry powder to dissolve, extract twice with an equal volume of 1.5% sodium hydroxide solution, add hydrochloric acid to the alkaline extract to adjust the pH to 4-8, produce precipitation, and let stand for 24 hour, filter with suction, wash with water until neutral, dry under reduced pressure (40°C-80°C, 0.05MPa), and pulverize into fine powder to obtain propolis flavonoid extract.
Embodiment 3
