Screening for biological activity and chemical composition of Euodia borbonica var. borbonica (Rutaceae), a medicinal plant in Reunion Island.

Three simple coumarins; scoparone, limettin and psoralen have been isolated as major components from the leaves of Euodia borbonica var. borbonica (Rutaceae) together with xanthoxylin, a common phenolic compound in Rutaceae family. Their structures were elucidated through GC/MS and NMR studies. A minor furocoumarin, bergapten, was also detected in the extracts. Preliminary biological tests on ethanolic leaf extracts did not show any activity.
