Abstract
From the roots of Clausena indica Oliv., a new coumarin, clausindine, has been isolated and shown to have the structure 6-(2,2-dimethylcyclopropyl)furo[3,2-g][1]benzopyran-7-one (I) mainly on spectroscopic evidence. The structure has been confirmed by a synthesis of dihydroclausindine (II). The furanoquinone, furo[3,2-g][1]benzopyran-4,7,9-trione (XII) has also been isolated from the roots of this plant.Keywords
