Embodiment 1
[0015] Embodiment 1: Preparation of anti-hepatitis drug freeze-dried powder injection
[0016] Methods include:
[0017] Grind rhizoma rhizome into coarse powder, weigh the coarse powder, soak with 5 times the amount of 90% ethanol for 24 hours, reflux extraction 4 times, each time for 1 hour, combine the extracts, recover ethanol under reduced pressure and concentrate to a relative density of 0.92- The clear paste of 1.02 is allowed to cool, filtered, and the filtrate is concentrated to a thick paste with a relative density of 1.16-1.20. Add distilled water to the thick paste, precipitate brown precipitated water, adjust the pH value to 2-3 with 10% hydrochloric acid solution, stir well, filter, wash 4-5 times with 10% hydrochloric acid solution, combine acid water, sodium carbonate Adjust the pH value to 9-10, precipitate a tan precipitate, filter, and extract the filter residue with 5 times the amount of chloroform for 5-6 times, combine the chloroform solution, add anhydr...
