Do extrato etéreo das folhas de Vellozia candida Mikan (Velloziaceae) foram isolados os flavonóis 3',4',5,7-tetraidroxi-3,6-dimetoxi-8-metilflavona e 3',4',5-triidroxi-3,6,7-trimetoxi-8-metilflavona. Estes compostos foram identificados através de seus dados espectrais, incluindo RMN 2D e EM-EM. O derivado 5-hidroxi-3,3',4',6,7-pentametoxi-8-metilflavona foi obtido por metilação usando diazometano.
From the leaves of Vellozia candida Mikan (Velloziaceae) the new flavonol 3',4',5,7-tetrahydroxy-3,6-dimethoxy-8-methylflavone and its known 7-O-methyl derivative, 3',4',5-trihydroxy-3,6,7-trimethoxy-8-methylflavone, were isolated and characterized by spectral data, including 2D NMR and tandem mass spectrometry experiments. The 5-hydroxy-3,3',4',6,7-pentamethoxy-8-methylflavone derivative was obtained by methylation with diazomethane.
