A New Furan-Coumarin from Clausena lansium

A new furan-coumarin, claulancoumarin (1), together with a known coumarin, clausenalansimin A (2), were isolated from the branches and leaves of Clausena lansium. Their structures were elucidated by spectroscopic analysis, including high-resolution mass spectroscopy, and IR, UV, and 1D and 2D NMR techniques.
