| dc.description | O fracionamento cromatográfico do extrato etanólico das folhas de Nectandra grandiflora resultou no isolamento de dois flavonóides glicosilados que apresentaram atividade antioxidante inibindo a oxidação do beta -caroteno em CCDC. As substâncias isoladas tiveram suas estruturas elucidadas através de técnicas espectrométricas de RMN uni- e bidimensional e foram identificadas como 3-O-beta -ramnosy kaempferol and 3-O-beta -ramnosylquercetina. | |
| dc.description | The bioassay-guided fractionation of the ethanol extract from Nectandra grandiflora leaves led to the isolation of two flavonol glycosides which inhibited the bleaching of beta -carotene on the TLC assay. Both compounds had their molecular structures elucidated by means of extensive use of uni- and bidimensional NMR techniques and were identified as 3-O-beta -rhamnosylkaempferol and 3-O-beta -rhamnosylquercetine. | |
