Embodiment 1
[0042]Embodiment 1, the preparation of monoammonium glycyrrhizinate compound
[0043] Take monoammonium glycyrrhizinate (C 42 h 65 NO 16 2H 2 O) 50g of raw material drug, add N,N-dimethylformamide / ethanol mixed solvent, wherein the ratio of monoammonium glycyrrhizinate raw material drug to mixed solvent is 1g:6ml, N,N-dimethylformamide in the mixed solvent The volume ratio of formamide to ethanol is 1:3, then add 0.10g of activated carbon, stir for adsorption, filter for decarbonization and sterilization to obtain a clear solution. Reflux at 45°C for 2 hours, cool down to 30°C, keep warm, and add chloroform dropwise at a stirring rate of 25r / min. The volume ratio of the chloroform to the mixed solvent is 3:1. After the dropwise addition, continue to keep warm and stir After 20 min, the stirring was stopped, the temperature was lowered to 0°C, and the mixture was allowed to stand at this temperature for 2 hours, filtered, washed with ethanol three times, and dried under red...

[0045] Embodiment 2, the preparation of monoammonium glycyrrhizinate compound
[0046] Take monoammonium glycyrrhizinate (C 42 h 65 NO 16 2H 2 O) 50g of raw material drug, add N,N-dimethylformamide / ethanol mixed solvent, wherein the ratio of monoammonium glycyrrhizinate raw material drug to mixed solvent is 1g:10ml, N,N-dimethylformamide in the mixed solvent The volume ratio of formamide to ethanol is 1:5, then add 0.10 g of activated carbon, stir for adsorption, filter for decarbonization and sterilization, and obtain a clear solution. Reflux at 50°C for 3 hours, cool down to 40°C, keep warm, and add chloroform dropwise at a stirring rate of 30r / min, the volume ratio of chloroform to mixed solvent is 7:1, continue to keep warm and stir after the dropwise addition After 30 minutes, the stirring was stopped, the temperature was lowered to 5°C, and the mixture was allowed to stand at this temperature for 6 hours, filtered, washed with ethanol three times, and dried under red...
Embodiment 3
[0048] Embodiment 3, the preparation of monoammonium glycyrrhizinate compound
[0049] Take monoammonium glycyrrhizinate (C 42 h 65 NO 16 2H 2 O) 50g of raw material medicine, add N,N-dimethylformamide / ethanol mixed solvent, wherein the dosage ratio of monoammonium glycyrrhizinate raw material medicine and mixed solvent is 1g:8ml, N,N-dimethylformamide in mixed solvent The volume ratio of formamide to ethanol is 1:4, then add 0.10g of activated carbon, stir for adsorption, and filter to decarbonize and sterilize to obtain a clear solution. Reflux at 47°C for 2.5h, cool down to 34°C, keep warm, and add chloroform dropwise at a stirring rate of 28r / min. The volume ratio of chloroform to mixed solvent is 5:1, and keep warm after the dropwise addition Stir for 25 minutes, then stop stirring, cool down to 2°C, let stand at this temperature for 3 hours, filter, wash with ethanol three times, and dry under reduced pressure for 3 hours to obtain the obtained product.
