Problems solved by technology

The main cause of cardiovascular and cerebrovascular diseases is caused by the abnormal metabolism of smooth muscle cells in the blood vessel wall. The blood vessel tissue and other tissues of the human body complete the metabolic process within a certain period, but due to the abnormal formation of new cell tissue, the blood vessel wall itself exists " "Defect" is therefore prone to inflammation and poor constriction of blood vessels, just like a dila

Abstract

The invention discloses application of an aleuritopteris argentea extract in preparation of medicines for treating cardiovascular and cerebrovascular diseases. Aleuritopteris argentea leaves are subjected to water-alcohol mixed extraction, extraction, membrane dialysis, column purification and regulation to obtain the aleuritopteris argentea extract with high activity. The aleuritopteris argentea leaves are adopted as the raw material, and effective ingredients of the aleuritopteris argentea are extracted and used for preparing medicines for treating cardiovascular and cerebrovascular diseases, so that the utilization of aleuritopteris argentea can be improved, and the treatment effect is remarkable.

Description

technical field [0001] The invention relates to the technical field of application of traditional Chinese medicines, in particular to the application of an extract of Tongjingcao in the preparation of medicines for treating cardiovascular and cerebrovascular diseases. Background technique [0002] Tongjingcao is the dry whole herb of the Chinese traveler plant, Argentia chinensis. Harvest in autumn, remove impurities and dry in the sun. Included in 1998 "Ministry of Health of the People's Republic of China Drug Standards Mongolian Drug Sub-volume". It is flat in nature and slightly bitter in taste, and has the effects of improving eyesight, healing wounds, stopping bleeding, promoting blood circulation and regulating menstruation, relieving cough, promoting dampness, detoxifying and reducing swelling, etc. . It is a commonly used drug in ethnic minority areas such as Tibet and Mongolia. However, the basic research on Tongjingcao is still very limited, which limits the su...
