Cuatro diterpenos (abietatrieno, ferruginol, acetil ferruginol e isopimarol) fueron aislados desde la corteza de Prumnopytis andina (Poepp. ex Endl.) de Laub. y dos diterpenos (sugiol y un diterpeno no identificado) desde la corteza de Austrocedrus chilensis (D. Don) Pic.- Serm et Bizz. Las estructuras fueron determinadas mediante métodos espectroscópicos (RMN uni- y bidimensional incluyendo DEPT, COSY y HETCOR). Se evaluó la actividad antimicrobiana de abietatrieno, ferruginol, el diterpeno no identificado y de los extractos frente a las cepas bacterianas: Staphylococcus aureus, Bacillus subtilis, Escherichia coli y Pseudomonas sp.

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