Objective:To demonstrate the vasodilatation activity of the coumarin-containing Angelica dahurica var.formosana and to further analyze active components in the herb extracts.Methods:(1) The vasodilatation effects induced by different extracts(cyclohexane,ethyl acetate,acetone,methanol,95%ethanol and water) of Angelica dahurica var.formosana on mouse thoracic aorta pre-contracted with phenylephrine were investigated. (2) The amount of imperatorin and isoimperatorin in each extract was measured by high-per...
