Embodiment 1
[0069] Take 1kg of Bo Luohui medicinal materials, cut them into 1-2cm pieces, add 8 liters of water to soak, adjust the pH of the solution to 2.0-3.0 with hydrochloric acid, stir frequently, soak for 16-24 hours, and filter by pressure to obtain 5 liters of extract; 5 liters of aqueous solution with a pH of 2.0-3.0 were soaked for 16 hours, and filtered to obtain 5 liters of extract. Combine the two extracts, add concentrated NaOH solution, adjust the pH of the extract to 6.0-7.0, let stand overnight to precipitate the alkaloids; filter and collect the filtrate; add NaOH solution to the filtrate to adjust the pH of the filtrate to 9.0-9.5 , and add NaCl, make the NaCl concentration in the filtrate reach 3.8%, stir to make NaCl dissolve completely, leave standstill overnight, make alkaloid precipitation; filter and collect precipitation, obtain the total alkaloid precipitate of plant origin of the present invention, yield (with Constant weight product) is 1.5%, after testing, c...
Embodiment 2
[0077] Take 2kg of medicinal materials, cut them into 1-2cm pieces, put them into the extraction container, add 8 liters of methanol, then add 8g of citric acid and 8ml of hydrochloric acid into the extraction container, soak for 16-24 hours, and filter with suction. Extract 5 liters; add 5 liters of methanol to the container, supplement 5 g of citric acid, 5 ml of hydrochloric acid, soak for 8-12 hours, and filter with suction to obtain 5 liters of extract. Combine the two extracts, adjust the pH to 6.0-7.0 with concentrated alkali, let stand overnight to precipitate the alkaloids; filter and collect the filtrate; continue to adjust the pH of the filtrate to 9.0-9.5 with concentrated alkali, and add 30% chlorine The zinc chloride solution is dissolved to make the concentration of zinc chloride in the filtrate reach 2%-4%, and the alkaloids are allowed to settle overnight to precipitate the alkaloids, and the precipitates are collected by filtration to obtain the total alkaloid...
Embodiment 3
[0081] Take 1kg of blood and water herbs, cut them into 1-2cm pieces, add 8 liters of water to soak, adjust the pH of the solution to 2.0-3.0 with hydrochloric acid, stir frequently, soak for 16-24 hours, filter by pressure, and get 5 liters of extract; add 5 liters to the filter residue. The solution was soaked in an aqueous solution with a pH of 2.0-3.0 for 16 hours, and filtered to obtain 5 liters of extract. Combine the two extracts, add concentrated Na 2 CO 3 solution, adjust the pH of the extract to 6.0-7.0, let stand overnight to precipitate the alkaloids; filter, collect the filtrate; add Na to the filtrate 2 CO 3 solution, adjust the pH of the filtrate to 9.0-9.5, and add NaCl to make the NaCl concentration in the filtrate reach 3.8%, stir to completely dissolve the NaCl, let stand overnight to precipitate the alkaloids; filter and collect the precipitate to obtain the total organisms derived from the plants of the present invention. Alkali precipitate, the yield (...
