Embodiment 1
[0039] [Example 1] Preparation of extract containing Scutellaria baicalensis and Atractylodes macrocephala
[0040] Take 250 kg each of Scutellaria baicalensis and Atractylodes macrocephala, add 1 ton of 50% ethanol, heat and reflux for extraction for 3 hours, filter, and add 1 ton of 5% ethanol to the dregs. Reflux for extraction for 2 hours, filter, and combine the two extracts. The solvent is recovered under reduced pressure, the temperature is 50-60 ° C, concentrated to 6 times the volume of the original medicinal material, the concentrated solution is diluted with 3 times hot water, centrifuged, and the precipitate is removed. The supernatant is taken and loaded on a D101 macroporous resin column (in Respectively use acid, alkali, water, alcohol to pre-treat the resin column before sample loading), rinse with 3BV pure water after sample loading, discard the aqueous solution, and use 3BV of 50% ethanol to elute, the flow rate of the eluent is 1.5 BV / h, collect the ethanol...
Embodiment 2
[0041] [Example 2] Preparation of extract containing Scutellaria baicalensis and Atractylodes macrocephala
[0042] Take 250 kg of Chinese medicinal materials Scutellaria baicalensis and Atractylodes macrocephala, add 1 ton of 80% ethanol, heat and reflux for extraction for 2 hours, filter, and add 1 ton of 80% ethanol to the dregs. Reflux for extraction for 2 hours, 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 concentrated solution with 5 times hot water, centrifuge, remove the precipitate, take the supernatant, and load it on a D101 macroporous resin column ( Respectively use acid, alkali, water, alcohol to pre-treat the resin column before sample loading), rinse with 3BV pure water after sample loading, discard the aqueous solution, and use 3BV of 80% ethanol to elute instead, and the eluent flow rate is 1.5BV / h, collect the et...
Embodiment 3
[0043] [Example 3] Preparation of extract containing Scutellaria baicalensis and Atractylodes macrocephala
[0044] Scutellaria baicalensis and rhizome of Atractylodes macrocephala each 1000g, pulverized to a particle size of 70 mesh, put into the extraction ax after drying, the extraction conditions are: the extraction pressure is 25Mpa, the temperature is 50°C, the separation conditions are: the first-stage decompression separation pressure is 8Mpa, The temperature is 50°C, the pressure of the secondary decompression separation is 7Mpa, the temperature is 45°C, and 80% ethanol is used as the entrainer. After dynamic operation for 5 hours, the total extract is obtained from the first decompression separation ax and the second decompression separation ax 6500ml, the extraction rate is 1.5%.
