RODRIGUES, Francisco E. A. et al. Diterpene and other constituents from Stemodia maritima (Scrophulariaceae). J. Braz. Chem. Soc. [online]. 2010, vol.21, n.8, pp.1581-1586. ISSN 0103-5053.

Um novo diterpeno, (5S*,8S*,9R*,10S*)-11β,12β-epoxi-9α-hidróxi-19(4→3) abeo-abieta-3,13-dieno-19,18-olideo, e as substâncias conhecidas estemodina, D-manitol, ácido betulínico, uma mistura de 3β-O-β-D-glicopiranosil-β-sitosterol e 3β-O-β-D-glicopiranosilestigmasterol, e 5,7,4'-triidróxi-3,8,3'-trimetoxiflavona, foram isolados das folhas e talos de Stemodia maritima. A elucidação estrutural de todas as substâncias baseou-se na interpretação de dados espectrais, principalmente RMN (1D e 2D) e espectrometria de massa (EM), envolvendo comparação com valores descritos na literatura.

Keywords : Stemodia maritima; Scrophulariaceae; diterpenes; steroids; flavonoids.
