Abstract:Erigeron breviscapus is a grass plant positae Erigeron breviscapus Hand.-Maz that lives many years. It contains more than fifty kinds of pound, such as flavone, tetrahydro-pyran-4-one, caffeate, phenolic acids. The most pound of Erigeron breviscapu is Scutellarin, which can clean out free radical, possess antioxidation function, protect heart and has a remarkable activity against thrombos formation and arrhythmia. Scutellarin can also protect cerebral nerves and brain tissue after cerebral ischemia and reperfusion, strengthen the detoxication of liver and keep the function of liver following diabetes. It can also protect nephridial tissue and improve the condition of hemorheology on diabetic nephropathy.
Key words:Erigeron breviscapus; Flavone; Scutellarin; Pharmacological function
