Abstract: Chromatographic fractionation of the extracts from the leaves of Ouratea hexasperma (Ochnaceae) afforded a new flavone dimer 5-hydroxy-7-methoxyflavone-(4'-O-8)-5,4' -dihydroxy-7-methoxyflavone besides known agathisflavone, 7-methylagathisflavone, epicatechin, 6-C-glycopyranosyl-luteolin and 3-O-glycopyranosyl-quercetin. The IR, NMR and mass spectra data analyses were used to establish the structures of these compounds.
O fracionamento cromatográfico dos extratos das folhas de Ouratea hexasperma (Ochnaceae) forneceu, além do novo biflavonóide 5-hidróxi-7-metoxiflavona-(4'-O-8)-5,4'-diidróxi-7 -metoxiflavona, a agathisflavona, 7-metilagathisflavona, epicatequina, 6-C-glicopiranosil-luteolina e a 3-O-glicopiranosil-quercetina já registradas na literatura. As estruturas desses compostos foram estabelecidas através da análise dos dados espectrométricos de IV, EM e RMN.
