Embodiment 1
[0025] Preparation of Active Part Components of APIs
[0026] Take 200g of the medicinal material Zijinlong, crush it into a coarse powder, soak it with 10% ethanol with a pH of 2.0 for 24 hours, filter the soaking liquid, continue to soak the dregs with 10% ethanol solution with a pH of 2.0 for 24 hours, filter, and take the filtrate , combined the two filtrates, concentrated the filtrate under reduced pressure at 60°C to a relative density of 1.05, no alcohol smell, cooled at room temperature, adjusted the pH of the concentrated medicinal solution to 8.0 with 10% sodium bicarbonate, extracted and alkalized with ethyl acetate The alkaloid reaction of the ethyl acetate extraction layer was negative, the ethyl acetate extract was combined, the ethyl acetate extract was extracted twice with distilled water, the water layer was discarded, the ethyl acetate layer was concentrated under reduced pressure, dried, and Zijin was obtained. Dragon extract 1.20g, set aside;
