Problems solved by technology

However, since gastric ulcer is a chronic disease, and the acid pump metabolizes quickly, it is necessary to insist on taking omeprazole for a long time, which leads to high cost of treatment and exceeds the affordability of many patients. Therefore, this drug is not yet suitable for large-scale use in China. scale clinical use

Embodiment 1

[0050] Example 1 Preparation of geranium extract containing corilagin

[0051] Take 2000g of Geranium macrorrhizum, crush it, add 7 times the amount of water, heat and decoct 2 times for 1.5 hours each time, combine the extracts, filter, collect the filtrate, pass the above sample liquid through the processed HPD400 50kg macroporous adsorption resin column for dynamic adsorption. After loading the column, the resin column is washed with 5 times the amount of resin water, and then eluted with 2 times the amount of resin with 95% ethanol to the end of the eluent, and the alcohol eluent is collected. Part of the alcohol eluate was concentrated to dryness under reduced pressure, and then precipitated with an appropriate amount of 95% ethanol overnight. After filtering and concentrating to dryness, 44 g of geranium extract containing corilagin was obtained, and the content of corilagin was determined to be 37% by high performance liquid chromatography.

Embodiment 2

[0052] Example 2 Preparation of geranium extract containing corilagin

[0053] Take 2000g of Geranium dahuricum DC, crush it, add 8 times the amount of water, heat and cook 3 times, 1.5 hours each time, combine the extracts, filter, collect the filtrate, pass the above sample solution through the processed HPD400 50kg macroporous adsorption resin column for dynamic adsorption. After loading the column, the resin column is washed with 8 times the amount of resin water, and then eluted with 4 times the amount of resin with 90% ethanol to the end of the eluent, and the alcohol eluent is collected. Part of the alcohol eluate was concentrated to dryness under reduced pressure, and then precipitated with an appropriate amount of 95% ethanol overnight. After filtering and concentrating to dryness, 38 g of geranium extract containing corilagin was obtained, and the content of corilagin was 23% by high performance liquid chromatography.

Embodiment 3

[0054] Example 3 Preparation of geranium extract containing corilagin

[0055] Take wild geranium (Geranium caroliniznum) and crush it, add 10 times the amount of water, heat and cook 3 times, 1.5 hours each time, combine the extracts, filter, collect the filtrate, pass the filtrate through the processed HPD400 50kg macroporous adsorption resin Column for dynamic adsorption. After the column loading is completed, the resin column is washed with 6 times the resin volume of water, and then eluted with 2 times the resin volume of 70% ethanol to the end of the eluent, and the alcohol eluent is collected. Part of the alcohol eluate was concentrated to dryness under reduced pressure, and then precipitated with an appropriate amount of 95% ethanol overnight. After filtering and concentrating to dryness, 40 g of geranium extract containing corilagin was obtained, and the content of corilagin was determined to be 29% by high performance liquid chromatography.
