Embodiment 1
[0022] A pharmaceutical composition, comprising: 100 parts of flavonoid extracts from bean root, 5 parts of baicalein, 5 parts of palmetine, and 5 parts of geniposide;
[0023] Wherein, the flavonoids extract of bean root adopts conventional reflux extraction method, and is prepared as follows:
[0024] Weigh 5 g of mountain bean root powder, add 80 mL of 70% ethanol, heat and reflux for extraction for 2 hours, then filter, and take the filtrate to obtain the extract; pass the extract through a 0.45 μm filter membrane, elute, and concentrate the eluate by rotary evaporation to obtain Soba root flavonoids extract; the elution process is specifically, use the pretreated D101 macroporous resin to load the sample, after the adsorption equilibrium, first deionized water elution and then 90% ethanol elution, after obtaining the eluent, in Rotary evaporation at 45°C followed by concentration; the volume ratio of the resin bed volume, the deionized water, and the 90% ethanol is 1:3:8;...
Embodiment 2
[0027] A pharmaceutical composition, comprising: 100 parts of flavonoid extracts from bean root, 10 parts of baicalein, 10 parts of palmetine, and 10 parts of geniposide;
[0028] Wherein, the flavonoids extract of bean root adopts ultrasonic extraction method, and is prepared as follows:
[0029] Weigh 5 g of mountain bean root powder, put it in an ultrasonic instrument, add 80 mL of 70% ethanol, and filter it after ultrasonic extraction for 30 minutes, and the filtrate is the extract; pass the extract through a 0.45 μm filter membrane, elute, and eluate Concentrate by rotary evaporation to obtain the flavonoids extract of bean root; the elution process is specifically, use the pretreated D101 macroporous resin to load the sample, after the adsorption equilibrium, first elute with deionized water and then with 90% ethanol to obtain The eluate was then concentrated by rotary evaporation at 45°C; the volume ratio of the resin bed volume, the deionized water, and the 90% ethanol...
Embodiment 3
[0032] A pharmaceutical composition, comprising: 100 parts of flavonoid extracts from bean root, 8 parts of baicalein, 8 parts of palmitate, and 6 parts of geniposide;
[0033] Wherein, the flavonoids extract of bean root is prepared as follows:
[0034] S1. Take the root slices of the mountain bean root and crush them through a 40-mesh sieve and soak them in ethanol with a volume fraction of 65% for 20 hours. After suction filtration, take the filter residue and dry it at 90° C. for 18 hours to obtain the root root of the mountain root;
[0035] S2. Add the root powder and enzyme to the extraction solvent in turn, stir evenly, react at 35°C for 40 minutes, and then filter to obtain the enzymolysis solution and residue; the root powder, the enzyme, the extraction The weight ratio of the solvent is 100:1.2:450, the enzyme is cellulase or pectinase; the extraction solvent is ethanol with a volume fraction of 70%;
[0036] S3. Put the enzymolysis residue in S2 in the extraction ...
