✦ Synopsis

The controversy with regard to the structures of the closely related polyisoprenylated phenollc compounds, garclnol, lsogarclnol, camboginol, cambogln, xanthochymol and lsoxdnthochymol is cleared by X-ray crystallographic analysis of the naturally occurring isogarcinol The unusual UV spectral characteristics of the chromophore of isogarcinol are discussed.

We have recently reported the isolation and suggested the structures of two compounds, E , garcinol (I) and isogarclnol (II) from Garcinla lndlca fruit rind' Rao and coworkers have LSOlated four closely related compounds, xanthochymol (III) and isoxanthochymol (IV) from G. xantho--chymus 2 3

and camboginol (I) and cambogln (V) from G. cambogla latex . Xanthochymol could be con-verted Into isoxanthochymol and camboglnol to cambogin and, so also, garclnol to isogarcinol 4
