The activity-guided fractionation of the hydroalcoholic extract of trunk bark of Cedrelopsis grevei led to the isolation of five coumarins, norbraylin (1), methyl-O-cedrelopsin (2), cedrecoumarin A (3), scoparone (4) and braylin (5) as a part of the constituents responsible for the vasorelaxing activity observed for the crude extract.
