Embodiment 1
[0042] The preparation method of pharmaceutical composition in the present embodiment comprises the following steps:
[0043] (1) Extraction: Soak the Acanthopanax senticosus medicinal material for 30 minutes with 8 times the volume of water, extract 3 times, each time for 1 hour, filter, combine the extracts, concentrate, and obtain the Acanthopanax senticosus water decoction 1.12 (measured at 80°C) ,spare;
[0044](2) Macroporous resin adsorption: take the Acanthopanax senticosus water decoction obtained in step (1), dilute it to a total flavonoid content of 10 mg / ml with purified water, after stirring evenly, the medicinal liquid is filtered through a microporous membrane to clarify, and the filtrate Apply macroporous resin column D101 at a flow rate of 1.2BV / h, then elute with 0.4 times column volume of purified water at the same flow rate, and discard; then elute with 4 times the volume of 50% ethanol, collect the eluate, and adjust The pH is 5.2, and the 50% eluate is c...
