Abstract:
The aerial parts of Phebalium clavatum yielded eight new 3-prenylated coumarins, phebaclavin A-H (1-8). Their structures were established on the basis of their NMR and mass spectral data. In addition, seven known compounds were also isolated, including two 8-geranyloxy linear furocoumarins previously obtained from Phebalium tuberculosum ssp. megaphyllum, included in the same section of the genus.
