• Sagittaria
• abietatrienes
• antimicrobial activity

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 abietatrienetype diterpenoid, 3 beta,7 alpha-dihydroxi-abieta-8,11,13-triene and the known 3 beta-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.
