ARAUJO, Renata M. de; LIMA, Mary Anne S.  and  SILVEIRA, Edilberto R.. Pterocarpans and a novel flavanone from harpalyce brasiliana roots. J. Braz. Chem. Soc. [online]. 2009, vol.20, n.5, pp.935-938. ISSN 0103-5053.

A nova '(-)-7,8,3',4'-tri-hidróxi-8-(3'',7''-dimetil-octa-2'',6''-dienoil)-flavanona foi isolada a partir do extrato etanólico das raízes de Harpalyce brasiliana, juntamente com os pterocarpanos conhecidos (-)-2-geranil-3-hidróxi-8,9-metilenodioxipterocarpano, harpalicina, medicarpina, maackiaina e as cabenegrinas A-I e A-II. Os metabólitos isolados foram caracterizados com base nos seus dados espectroscópicos, principalmente RMN uni e bidimensional.

Keywords : Harpalyce brasiliana; flavanone; pterocarpans; NMR assignments.
