Uma nova flavona prenilada, 2,8-dihodroxi-3,10-dimetoxi-6-(2-metil-1-propeno-1-il)6H,7H-[1]benzopirano[4,3-b][1]-benzopirano-7-ona, juntamente com 24 compostos conhecidos foram isolados do extrato bruto em acetona das raizes de um hibrido entre Artocarpus heterophyllus e Artocarpus integer. Suas estruturas foram determinadas pelos dados de espectroscopia da ressonância magnetica nuclear (NMR) 1D e 2D. Avaliaram-se as atividades antioxidante e bactericida dos compostos isolados. O novo composto mostrou atividade antioxidante potente com relacao a DPPH • e superoxido com valores de IC50 de 0,033 e 0,125 mg mL -1 , respectivamente. One new prenylated flavone, 2,8-dihydroxy-3,10-dimethoxy-6-(2-methyl-1-propen-1-yl)6H,7H-[1]benzopyrano[4,3-b][1]-benzopyran-7-one, together with 24 known compounds were isolated from crude acetone extract from the roots of a hybrid between Artocarpus heterophyllus and Artocarpus integer. Their structures were determined by 1D and 2D nuclear magnetic resonance (NMR) spectroscopic data. The antioxidant and antibacterial activities of the isolated compounds were evaluated. The new compound showed potent antioxidant activity against DPPH
