Abstract
A new naphthopyranone dimer (I) named planifolin was isolated from a methyl ene chloride extract of the capitula of Paepalanthus planifolius. The struc ture of 1 has been determined by chemical and spectroscopic means. In addit ion, a known dihydronaphthopyranone glycoside and seven known flavonoids we re isolated from an ethanolic extract of the leaves of P. planifolius.
