Embodiment 1

[0050] Embodiment 1 prepares the geranium extract containing corilagin

[0051] Take 2000g of Geranium macrorrhizum, pulverize it, add 7 times the amount of water, heat and decoct twice for 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 the column loading is completed, the resin column is washed with 5 times the amount of resin in water, and then eluted with 2 times the amount of resin in 95% ethanol until the end of the eluate, and the alcohol eluate is collected. The ethanol eluate was partially concentrated to dryness under reduced pressure, and then precipitated with an appropriate amount of 95% ethanol overnight. Filtrate and concentrate to dryness to obtain 44 g of geranium extract containing corilagin, in which the content of corilagin is 37% as detected by high performance liquid chromatography.

Embodiment 2

[0052] Embodiment 2 prepares the geranium extract containing corilagin

[0053] Take 2000g of Geranium dahuricum DC, pulverize it, add 8 times the amount of water, heat and decoct 3 times for 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 the column loading is completed, the resin column is washed with 8 times the amount of resin in water, and then eluted with 4 times the amount of resin in 90% ethanol until the end of the eluate, and the alcohol eluate is collected. The ethanol eluate was partially concentrated to dryness under reduced pressure, and then precipitated with an appropriate amount of 95% ethanol overnight. Filtrate and concentrate to dryness to obtain 38 g of geranium extract containing corilagin, in which the content of corilagin is 23% as detected by high performance liquid chromatography.

Embodiment 3

[0054] Embodiment 3 prepares the geranium extract containing corilagin

[0055] Get wild geranium (Geranium caroliniznum) and pulverize, add 10 times the amount of water, heat and decoct 3 times, each time for 1.5 hours, combine the extracts, filter, collect the filtrate, pass the above-mentioned filtrate through the processed HPD40050kg 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 eluate, and the ethanol eluate is collected. The ethanol eluate was partially concentrated to dryness under reduced pressure, and then precipitated with an appropriate amount of 95% ethanol overnight. Filtration and concentration to dryness obtained 40 g of geranium extract containing corilagin, and the content of corilagin in it was 29% as detected by high performance liquid chromatography.
