Embodiment 1
[0027] 1. Take 3.0 kg of Huangqin Decoction medicinal materials according to the prescription, add 2 times (V / W) crude drug amount of 70% ethanol solution, stir evenly, and place for 8 hours. Then add 5 times of 70% ethanol solution and heat to reflux for 1.5 hours, filter and repeat twice, and combine the extracts.
[0028] 2. The above extract was concentrated under reduced pressure at 50-75°C under the condition of 0.05MP to obtain an extract with a specific gravity of 1.10 (60°C).
[0029] 3. Add the extracted extract obtained above to a chromatographic column equipped with 3.0kg D-101 macroporous adsorption resin, and elute with 7 times column volume of water, followed by elution with 6 times column volume of 80% ethanol solution . Collect the 80% ethanol eluate.
[0030] 4. Concentrate the 80% ethanol eluate above at 0.05MP under reduced pressure at 70° C. to an extract with a relative density of 1.20 (60° C.), and dry it at 75° C. under reduced pressure to obtain 323 ...
