CUCA SUAREZ, Luis Enrique; COY BARRERA, Carlos Andrés; COY BARRERA, Ericsson David  e  LOZANO MORENO, José Manuel. Antibacterial activity of terpenes and alkaloids isolated from three Colombian plants. Rev Cubana Farm [online]. 2011, vol.45, n.2, pp. 275-282. ISSN 1561-2988.

The antibacterial potential of 14 compounds obtained from three native Colombian species( [Pleurothyrium cinereum [van der Werff], Esenbeckia alata [Karst & Triana], Reputia heptaphylla [Pittier]) was assessed by agar diffusion method versus four bacterial species: Enterococcus faecalis 29212, Staphylococcus aureus 6539, Escherichia coli 25922 and Salmonella tiphymurium 14028s. The assessed compounds showed activity versus strains at different levels, maintaining a trend and selectivity according the base nucleus. The 4-methoxi-1-methyl-quinolin-2-(1H) alkaloid, other (8) was the compound with the highest activity.
