Abstract
Four diterpenes (abietatriene, ferruginol, acetyl ferruginol and isopimarol ) were isolated from the bark of Prumnopytis andina (Poepp, ex Endl.) de La ub. and two diterpenes (sugiol and an unidentified diterpene) from the bark of Austrocedrus chilensis (D. Don) Pie. Serm. et Bizzarri. The structures were established by spectroscopic methods (1D and 2D NMR techniques includi ng DEFT, COSY and HETCOR). Abietatriene, ferruginol, the unidentified diter pene and the extracts were tested for antimicrobial activity against standa rd bacterial strains (Staphylococcus aureus, Bacillus subtilis, Escherichia coli and Pseudomonas sp.).
