Breviscapinum and extracting process thereof from erigeron breviscapus

摘要

An extracting process for extracting breviscapinum from erigeron breviscapus, wherein the breviscapinum has a chemical structure of 4',5, 6-trishydroxyflavone-7-glucuronide that can increases cerebral blood flow for significantly decreasing cerebrovascular resistance; raises permeability of blood-brain barrier, increases nutritional blood flow of myocardium; raises immune function of body macrophage cell and counteraction against blood and oxygen depletion induced by hypophyseal pitutrin and thrombocyte agglutination induced by adenosine diphespate inhibiting internal thrombosis and promoting activity of cellulose dissolution; and increases peripheral and coronary bleed flow, effective for sequelas induced by cerebrovascular accident: palsy, coronary heart disease and angina pectoris.
