Resumo: The biflavonoid 2",3"-dihydroochnaflavone, isolated from the Luxemburgia species (Ochanaceae), was treated with diazomethane to obtain the trimethyl-ether that was treated with pyridine/acetic anhydride to yield a new derivative, 5-acetil-7,4'-dimethyl-flavone-(3'→O-4'")-5"-acetil-7"-methyl-flavanone. The complete ¹H and 13C NMR data assignments of the new derivative were made by the one- and two-dimensional spectral analysis.
