Vasorelaxing properties and bio-guided fractionation of Cedrelopsis grevei.[Pubmed:
12624830]
METHODS AND RESULTS:
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 (O-Methylcedrelopsin,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.
