Embodiment 1
[0065] Crush the medicinal material Gelkins into a coarse powder, add 8-10 times the amount (based on the weight of the raw material) of ethanol for extraction, filter to obtain the filtrate, repeat the extraction of the filter residue 1-2 times, and combine the extracts; concentrate under reduced pressure, recover ethanol, to The relative density is 1.10-1.15 to obtain a concentrated solution; an equivalent amount of water is added to the concentrated solution to adjust the pH of the solution to be 2.0-3.0 to obtain a total alkaloid salt solution of Gelcyonium alkaloids; an equivalent amount of ( (in solution volume) chloroform, adjust the pH of the mixed solution to 10.0 with 40% alkali solution, vibrate vigorously for 15-20min, let stand for 20-30min, and separate the chloroform phase; repeat the chloroform extraction step 1-2 times, and combine the chloroform phase; The remaining liquid was extracted twice with an equal amount of ethyl acetate, and the extracts were combine...
Embodiment 2
[0073] Pulverize the Gypsy medicinal material, add an acidic (PH2. The second filtrate was added with 40% lye, the pH was adjusted to 10, and the alkaloid was allowed to stand overnight. Filtration to obtain gynecine alkaloid precipitation. Suspend the precipitate in 10 times the amount of acidic aqueous solution (pH 2.0), dissolve it, and obtain the total alkaloid solution of kelp. Add an equal amount (volume ratio) of chloroform to the solution, and adjust the pH of the mixed solution to 9-10, oscillate, stand still, separate the chloroform phase, repeat the chloroform extraction once, and combine the chloroform solution twice; the water phase is extracted with an equal amount of ethyl acetate 2 times, combined ethyl acetate solution. Under reduced pressure, recover chloroform and ethyl acetate respectively to 1 / 4 of the original volume to obtain the total alkaloid extract of citronella; dissolve the two extracts with acidic aqueous solution to obtain the total alkaloid aq...
Embodiment 3
[0076]Pulverize the medicinal material Gelkins, add 1-1.5 times the amount of raw materials in lye (PH=10) to moisten, airtightly dry after 24 hours, add 6-8 times the amount of raw materials in chloroform and soak for 12 hours, percolate, and add chloroform to the filter residue Chloroform volume meter) continue to soak for 8h, press filter, combine two filtrates, recover chloroform under reduced pressure to 1 / 2 of the original volume; add an equivalent amount of water to the concentrated chloroform solution, adjust the pH of the mixed solution to 2.0 with 40% hydrochloric acid solution , fully oscillated for 15 minutes and left to stand for 30 minutes to separate the water phase; repeat the water extraction step once, combine the water extracts, carefully adjust the pH of the aqueous solution to 6.0-7.0, and add a non-polar adsorption resin of 1 / 8 (parts by weight) of the original medicinal material , slowly stirred and adsorbed overnight at room temperature, filtered to obta...
