Isolation and identification of morin in Brazilian honey from Apis mellifera

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.
