Isolamento e identifica??o da morina em mel brasileiro de Apis mellifera

摘要

The flavonoid fraction was purified by a combination of chromatography on Amberlite XAD-2 and preparative silica gel TLC. Morin (3, 5, 7, 2', 4'- pentahydroxyflavone) was the only flavonol found in honey from Brazilian Citrus sp.. The structure of morin was determined on the basis of UV and 1H and 13C NMR spectral data together with literature references. This is the first report on the isolation of morin from Brazilian Citrus honey.
