Embodiment 1
[0110] Preparation of total flavonoids from Hedyotis diffusa and Astragalus total polysaccharides from Hedyotis diffusa
[0111] Preparation method: Take Hedyotis diffusa and Radix Astragali (3:1, w / w), add 12 times the amount of 80% ethanol to reflux and extract twice, each time for 1.5 hours, filter, and use the dregs for later use; combine the filtrates, and recover under reduced pressure Ethanol, add water to dilute the concentrated solution, pass through the macroporous resin column according to the amount of resin: medicinal material amount 1:1, first elute with 6 times the amount of deionized water, then elute with 8 times the amount of 70% ethanol, collect the eluate, reduce The ethanol is recovered under pressure, concentrated, and dried to obtain the active parts of total flavonoids. Take the above medicinal residues, add 15 times the amount of water to extract 3 times, each time for 2 hours, filter, combine the filtrates, concentrate under reduced pressure to 1g cru...
Embodiment 2
[0113] Preparation of Denon Small Peptide
[0114] Preparation method: Take Tianlong, crush it properly, pass through a 50-mesh sieve, add 10 times the amount of water to homogenate for 10 minutes, heat and boil for 15 minutes, let cool to room temperature, use hydrochloric acid to adjust the pH to 2, and then add pepsin with 3% substrate amount, Enzymolysis at 45°C for 3 hours, then use 20% sodium hydroxide solution to adjust the pH to 8, add trypsin with 1% substrate amount, and enzymatic hydrolysis at 50°C for 4 hours, stir frequently and adjust the pH to 8-8.5 Within the range, after the enzymolysis is completed, continue to heat up and boil for 5 minutes, let cool, centrifuge, concentrate under reduced pressure to a clear paste of 4:1 (ml / g), add solid paraffin with 40% medicinal material, heat and melt, and stir evenly, and refrigerate Overnight, take out the paraffin layer, filter, the filtrate is concentrated under reduced pressure, and dried to obtain the obtained pro...
Embodiment 3
[0116] Preparation of total flavonoids and total polysaccharides of Astragalus barbatae
[0117] Preparation method: Take Scutellaria barbata and Radix Astragali (3:1, w / w), add 10 times the amount of 60% ethanol to reflux and extract twice, each time for 1.5 hours, filter, and use the dregs for later use; combine the filtrates, and recover ethanol under reduced pressure , add water to dilute the concentrated solution, pass through the macroporous resin column according to the amount of resin: medicinal material amount 1:1, first elute with 8 times the amount of deionized water, then elute with 10 times the amount of 70% ethanol, collect the eluate, and decompress The ethanol is recovered, concentrated, and dried to obtain the effective fractions of total flavonoids. Take the above medicinal residues, add 20 times the amount of water to extract 3 times, each time for 2 hours, filter, combine the filtrates, concentrate under reduced pressure to 1g crude drug / ml, add ethanol to ...
