Abstract
The invention belongs to the medicine industry, in particular to application of cat's-foot or cat's-foot extract and a method for preparing the cat's-foot extract. A great deal of tests prove that the cat's-foot or the cat's-foot extract has the anticoagulation efficiency and the thrombolysis efficiency. In addition, the inventor also provides two methods for preparing the cat's-foot extract, wherein the method A comprises the following steps of: heating dried cat's-foot with alcohol for reflux, extracting and filtering; adding water to residual medicine dregs after the filtrate is discarded, heating for reflux, extracting and then refiltering; concentrating the filtrate into a paste to obtain the extract; the method B comprises the following steps of: heating the dried cat's-foot with water for reflux, extracting and filtering; concentrating the filtrate into a paste to obtain the extract. The invention has the advantages of simple and easy preparation process; the prepared extract has strong drug action, wide safety range, controllable quality and the like.
