Embodiment 1
[0042] Example 1 The preferred preparation method of total alkaloids of Corydalis and its application in the preparation of drugs for the treatment of coronary heart disease
[0043] Take the Corydalis Corydalis medicinal material, crush it into a coarse powder passing through a 20-mesh sieve, soak it with 0.5% hydrochloric acid solution 16 times the weight of the medicinal material for 24 hours, and then percolate. Elution, then elution with 10% ethanol 3 times the volume of the resin to remove impurities, and finally elution with 50% ethanol 12 times the volume of the resin, collect the eluate, concentrate under reduced pressure at 60 ° C to a relative density of 1.10 to 1.20 The extract is spray-dried and pulverized to obtain the effective fraction of the total alkaloids of Corydalis Corydalis. The content of total alkaloids is 85%.
[0044] The following pharmacological test is carried out for the effective parts of the obtained total alkaloids of Corydalis Corydalis, tha...
Embodiment 2
[0055] Example 2 The preferred preparation method of total alkaloids of Corydalis Corydalis
[0056] Take the Corydalis Corydalis medicinal material, crush it into a coarse powder passing through a 20-mesh sieve, soak it with 0.5% sulfuric acid solution 16 times the weight of the medicinal material for 24 hours, and then percolate. The percolation liquid is absorbed by a D101 macroporous adsorption resin column. Eluted with water, then eluted with 20% ethanol 4 times the volume of the resin to remove impurities, and finally eluted with 70% ethanol 10 times the volume of the resin, collected the eluate, concentrated under reduced pressure at 60°C to a relative density of 1.10-1.20 The extract is vacuum-dried and pulverized to obtain the effective fraction of the total alkaloids of Corydalis Corydalis. The content of total alkaloids is 80%.
Embodiment 3
[0057] Example 3 The preferred preparation method of Corydalis total alkaloids
[0058] Take the Corydalis Corydalis medicinal material, crush it into a coarse powder passing through a 20 mesh sieve, soak it with 1% hydrochloric acid solution of 14 times the weight of the medicinal material for 12 hours, and then percolate. The percolation liquid is absorbed by a Dm301 macroporous adsorption resin column. Eluted with water, then eluted with 40% ethanol 2 times the volume of the resin to remove impurities, and finally eluted with 90% ethanol 6 times the volume of the resin, collected the eluate, concentrated under reduced pressure at 60°C to a relative density of 1.10-1.20 The extract is freeze-dried and pulverized to obtain the effective fraction of the total alkaloids of Corydalis Corydalis. The content of total alkaloids is 62%.
