title: Coumarins from Clausena anisum-olens Merr.
abstract: Seven coumarins, including a new O-terpenoidal coumarin, named anisumarin (1), were isolated from Clausena anisum-olens Merr. The structure of this new coumarin was identified as 7-{(E)-4-[(4-acetoxymethyl-1,5-dihydro-5-oxo)-2H-furylium-2-yl]-3-methyl-2-butenoxy}-8-methoxycoumarin on the basis of an extensive spectroscopic analysis.
