Embodiment 1
[0039] [Example 1] Preparation of extracts containing Scutellaria baicalensis and Atractylodes Rhizoma
[0040] Take 250 kg each of Chinese medicinal materials Scutellaria baicalensis and Atractylodes Rhizoma, add 1 ton of 50% ethanol, heat under reflux for extraction for 3 hours, filter, and continue to add 1 ton of 5% ethanol to the medicinal residues. Reflux extraction for 2h, filter, and combine the two extracts. Recover the solvent under reduced pressure, at a temperature of 50-60 °C, concentrate to 6 times the volume of the original medicinal material, dilute the concentrate with 3 times of hot water, centrifuge, remove the precipitation, take the supernatant, and load it on a D101 macroporous resin column (in The resin column was pre-treated with acid, alkali, water and alcohol before sample loading), after sample loading, rinsed with 3BV pure water, discarded the aqueous solution, and eluted with 50% ethanol of 3BV instead, and the eluent flow rate was 1.5 BV / h, colle...
Embodiment 2
[0041] [Example 2] Preparation of extracts containing Scutellaria baicalensis and Atractylodes Rhizoma
[0042] Take 250 kg each of Chinese medicinal materials Scutellaria baicalensis and Atractylodes Rhizoma, add 1 ton of 80% ethanol, heat and reflux for extraction for 2 hours, filter, and continue to add 1 ton of 80% ethanol to the medicinal residues. Reflux extraction for 2h, filter, and combine the two extracts. Recover the solvent under reduced pressure, at a temperature of 50-60 °C, concentrate to 10 times the volume of the original medicinal material, dilute the concentrate with 5 times of hot water, centrifuge, remove the precipitation, take the supernatant, and load it on a D101 macroporous resin column (in The resin column was pre-treated with acid, alkali, water and alcohol before sample loading), after sample loading, rinsed with 3BV pure water, discarded the aqueous solution, and eluted with 3BV 80% ethanol instead, and the eluent flow rate was 1.5 BV / h, collect ...
Embodiment 3
[0043] [Example 3] Preparation of extracts containing Scutellaria baicalensis and Atractylodes Rhizoma
[0044] Scutellaria baicalensis and Atractylodes Rhizoma rhizomes are each 1000g, pulverized to a particle size of 70 mesh, dried and put into the extraction axe. The temperature is 50°C, the secondary decompression separation pressure is 7Mpa, the temperature is 45°C, and 80% ethanol is the entrainer. After 5 hours of dynamic operation, the total extract is obtained from the primary decompression separation axe and the secondary decompression separation axe. 6500ml, the extraction rate is 1.5%.
