External Accumulation of Biflavonoids on Gymnosperm Leaves

Biflavonoids are well known to occur in many Gymnospermae. Here we report on their occurrence in epicuticular material of a number of species. Several compounds are charac­terized by detailed NMR studies and FAB-MS. They are identified as amentoflavone, bilobe-tin, podocarpus-flavone A, sciadopitysi...

Zusammenfassung:Biflavonoids are well known to occur in many Gymnospermae. Here we report on their occurrence in epicuticular material of a number of species. Several compounds are charac­terized by detailed NMR studies and FAB-MS. They are identified as amentoflavone, bilobe-tin, podocarpus-flavone A, sciadopitysin, dihydrosciadopitysin and cupressuflavone.
