Embodiment 1
[0071] Prescription of medicinal materials: Danshen slices 2000g, safflower 1000g.
[0072] Extract preparation:
[0073] Take the Danshen medicinal material, crush it into a coarse powder, heat and decoct it with an aqueous solution containing 0.1% sodium bisulfite to extract 4 times, each time for 70 minutes, combine the extracts and centrifuge at 8000 rpm, and adjust the pH value of the centrifuged solution with acid solution To 3, refrigerate, filter, add the filtrate to the AB-8 macroporous absorbent resin column that has been processed, first wash away impurities with water 3 times the volume of the resin column, and then elute with 5 times the volume of 30% ethanol, Collect the ethanol eluate, recover the solvent under reduced pressure until the ratio of the amount of the medicinal solution to the crude drug is 1:2, add n-butanol saturated with water 4 times, combine the extracts, recover the solvent under reduced pressure until dry, and obtain the Danshen extract;
