Two new furanocoumarins, 5-(1,1-dimethylallyl)-8-methyl psoralen (1) and 2-O-acetyl oxypeucedanin hydrate-3-methyl ether (2), were isolated from the root heartwood of Ficus carica Linn. together with three known furanocoumarins, two triterpenoids, two long-chain compounds, and a steroid. Their structures and relative confi gurations were elucidated by spectroscopic methods (IR, HR-ESI-MS, and NMR) and by comparison of their NMR spec- tral data with those of related compounds.

Key words: Ficus carica, Furanocoumarins, Triterpenoids
