Embodiment example 1
[0035] The first step is to grind Pulsatilla pulsatillae into coarse powder, soak in water for 0.5-2h, heat and reflux extract 6-12 times the amount for 2-3 times, each time for 1-3h, filter, and combine the filtrates. The above-mentioned filtrate was concentrated under reduced pressure at 50-70°C to 0.5-1.0g raw medicinal materials / mL, refrigerated overnight at 0-4°C, separated from the gel, and filtered to obtain Pulsatilla pulsatilla extract.
[0036] In the second step, add sodium hydroxide solution to the aqueous solution of Pulsatillae extract to adjust the pH to 10-13, heat and boil for 4-10 hours, measure the pH every 30-60 minutes, keep it at pH 10-13, let it cool, add hydrochloric acid solution, and adjust the pH 3-7, centrifuge, remove the precipitate, and obtain the hydrolyzate of Pulsatilla radix extract
[0037] In the third step, the hydrolyzate of Pulsatillae extract is adsorbed by D101 or AB-8 or ADS-17 macroporous resin, eluted with water, 30-40% ethanol, 50-...
Embodiment example 2
[0046] The first step is to grind Pulsatilla pulsatillae into coarse powder, soak in 10-45% ethanol for 0.5-2h, heat and reflux extract 6-12 times the amount for 2-3 times, each time for 1-3h, filter, and combine the filtrates. The above-mentioned filtrate was concentrated under reduced pressure at 50-70°C to 0.5-1.0g raw medicinal materials / mL, without alcohol smell, refrigerated overnight at 0-4°C, gel separated, filtered, and Pulsatilla pulsatilla extract was obtained.
[0047] In the second step, add sodium hydroxide solution to the aqueous solution of Pulsatillae extract to adjust the pH to 10-13, heat and boil for 4-10 hours, measure the pH every 30-60 minutes, keep it at pH 10-13, let it cool, add hydrochloric acid solution, and adjust the pH 3-7, centrifuge, remove the precipitate, and obtain the hydrolyzate of Pulsatilla radix extract
[0048] In the third step, the hydrolyzate of Pulsatillae extract is adsorbed by D101 or AB-8 or ADS-17 macroporous resin, eluted with...
Embodiment example 3
[0057] The first step is to grind Pulsatilla pulsatillae into coarse powder, soak in 45-95% ethanol for 0.5-2h, heat reflux to extract 6-12 times the amount for 2-3 times, each time for 1-3h, filter, and combine the filtrates. The above-mentioned filtrate was concentrated under reduced pressure at 50-70°C to 0.5-1.0g raw medicinal materials / mL, without alcohol smell, refrigerated overnight at 0-4°C, gel separated, filtered, and Pulsatilla pulsatilla extract was obtained.
[0058] In the second step, add sodium hydroxide solution to the aqueous solution of Pulsatillae extract to adjust the pH to 10-13, heat and boil for 4-10 hours, measure the pH every 30-60 minutes, keep it at pH 10-13, let it cool, add hydrochloric acid solution, and adjust the pH 3-7, centrifuge, remove the precipitate, and obtain the hydrolyzate of Pulsatilla radix extract
[0059] In the third step, the hydrolyzate of Pulsatillae extract is adsorbed by D101 or AB-8 or ADS-17 macroporous resin, eluted with ...
