Method for preparing non-alkaloids part of subprostrate sophora root
A non-alkaloid and mountain bean technology, which is applied in the field of preparation of the non-alkaloid part of mountain bean root, can solve the problem that the effect is not as obvious as the "Ganyanling injection" prepared by direct extraction with water, and achieve stable substance content Controllable, simple preparation process and low cost

Embodiment 1
[0019] Take 1000g of 40-mesh to 200-mesh mountain bean root medicinal powder, add 6 times the amount of water for the first time, reflux extraction for 1 hour, and filter.
[0020] The dregs were then reflux extracted with water 4 times the amount of the medicinal material for 1 hour, and then filtered. The combined filtrates were concentrated under reduced pressure to 250 mL. At 4°C, add 95% ethanol to the concentrated solution, stir to adjust the alcohol concentration of the solution to 50%, and let it stand for 6 hours; filter to remove insoluble matter. Concentrate the filtrate to 250mL, and separate it with a cross-linked polystyrene-based strong acid resin, the model of which is 001×7, and elute with deionized water; collect the water eluate until the eluate is neutral and colorless, and concentrate under reduced pressure The eluate is in the form of an extract, dried in a vacuum or freeze-dried into a dry powder, and the non-alkaloid part of the root of the mountain be...
Embodiment 2
[0023] Take 1000g of 40-mesh to 200-mesh mountain bean root medicinal powder, add 10 times the amount of water for the first time, reflux extraction for 2 hours, and filter. The dregs were then reflux extracted with water 6 times the amount of medicinal materials for 1.5 h, and then filtered. The operation was repeated once, and the combined filtrates were concentrated under reduced pressure to 300 mL. At 20°C, add 95% ethanol to the concentrated solution, stir to adjust the alcohol concentration of the solution to 70%, and let it stand for 8 hours; filter to remove insoluble matter. Concentrate the filtrate to 250mL, and separate it with a cross-linked polystyrene-based strong acid resin, the model of which is 001×7, and elute with deionized water; collect the water eluate until the eluate is neutral and colorless, and concentrate under reduced pressure The eluate is in the form of an extract, dried in a vacuum or freeze-dried into a dry powder, and the non-alkaloid part of ...
Embodiment 3
[0026] Take 1000g of 40-mesh to 200-mesh mountain bean root medicinal powder, add 15 times the amount of water for the first time, reflux extraction for 3 hours, and filter.
[0027] The dregs were then reflux extracted with water 8 times the amount of medicinal materials for 1.5 h, and then filtered. The operation was repeated twice, and the combined filtrate was concentrated under reduced pressure to 500 mL. At 30°C, add 95% ethanol to the concentrated solution, stir to adjust the alcohol concentration of the solution to 90%, and let it stand for 10 hours; filter to remove insoluble matter. Concentrate the filtrate to 250mL, and separate it with a cross-linked polystyrene-based strong acid resin, the model of which is 001×7, and elute with deionized water; collect the water eluate until the eluate is neutral and colorless, and concentrate under reduced pressure The eluate is in the form of an extract, dried in a vacuum or freeze-dried into a dry powder, and the non-alkaloid...
