Abstract Aniba species (Lauraceae) are characterized by the presence of neolignans or of 6-aryl (or 6-styryl-) 2-pyrones. Flavonoids occur either together with pyrones or, in rare cases, as predominant micromolecular type. The branch wood of an Aniba species from Marapi, Parú do Oeste River, near Tiriós (Para State), constitutes such a case. It contains 5,7,8,3'.4',5'-hexam-thoxyflavone, obtained for the first time from a natural source.
