[0020] The preparation method of the fern extract of the present invention is as follows:
[0021] Take the dried root tubers of Ferns, crush them, add 8 times the amount of 90% ethanol, reflux at 80°C for 2 hours, repeat twice, combine the extracts, concentrate under reduced pressure to a specific gravity of about 1.40g / ml, and obtain the alcoholic extract. Disperse the extract with 3 times the amount of water, sequentially extract 3 times with petroleum ether, ethyl acetate and n-butanol equivalent to 1 / 3 volume of the water dispersion system, combine the n-butanol liquid, concentrate under reduced pressure, and freeze-dry to obtain normal butanol site.

Abstract
The invention relates to an extractive of a potentilla anserina in the application of preparing the medicine for curing ischemic disease of heart and brain, and curing ischemia reperfusion injury of heart and brain. The ischemia and the ischemia reperfusion injury are the diseases which are seriously affected the health of human beings. With the change in the ageing of population and the life style of people, the category of disease has become a major disease which threatens the life of human being, especially the ischemia reperfusion injury is the common complicating disease of the percutaneous intervention of the present clinical cardiovascular PCI and bypass grafting. In the recent years, the scholars both abroad and at home take a lot of researches on using traditional Chinese medicine to cure the diseases of the ischemia and the ischemia reperfusion injury, and the researches show that the traditional Chinese medicine has strong tolerance to oxygen-poor organism and has good protection for the ischemia and the ischemia reperfusion injury. The extractive of the potentilla anserina in the invention proves that the traditional Chinese medicine has remarkable effects in curing the diseases of the ischemia and the ischemia reperfusion injury.
Description
technical field [0001] The invention relates to a pharmaceutical product, which is composed of the extract of Bracken japonica and a pharmaceutically acceptable carrier, and the product can be used for preventing and treating ischemic diseases.
