Química Nova, São Paulo, v. 33, n. 1, p. 30-32, 2010.0100-4042e- 1678-7064http://repositorio.bc.ufg.br/handle/ri/15305The antimicrobial properties of the hexane, hexane/EtOAc and methanol fractions of the fresh petioles of Sagittaria montevidensis ssp montevidensis (Alismataceae) were evaluated against fungi and Gram-negative and Gram-positive bacteria. A new abietatriene-type diterpenoid, 3β,7α–dihydroxi-abieta-8,11,13-triene and the known 3β-hydroxy-abieta-8,11,13-trien-7-one were isolated from the most active fraction tested and the structures of these compounds were elucidated by data including IR, EIMS, and 1D and 2D NMR spectra.engAcesso AbertoSagittariaAbietatrienesAntimicrobial activityArtigo
