A New coumarin from Citrus paradisi Macf.
Phytochemical examination of the peel of grapefruit resulted in the isolation of five compounds namely friedelin, beta -sitosterol, 7(3',7',11',14'-tetramethy)pentadec-2',6',10'-trienyloxycoumarin, limonin and cordialin B. These compounds have been characterized on the basis of spectral data, and 7(3',7',11',14'-tetramethy)pentadec-2',6',10'-trienyloxycoumarin is a hitherto unreported compound.
