TANAKA, Clara M. A. et al. Abietatrienes diterpenoids from Sagittaria montevidensis SSP Montevidensis. Quím. Nova [online]. 2010, vol.33, n.1, pp. 30-32. ISSN 0100-4042.  http://dx.doi.org/10.1590/S0100-40422010000100006.

The 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.
