“…These forests regulate water interception, store carbon, and increase soil fertility (Mancipe-Murillo et al, 2018;Melissa and Torres, 2016;Quintero et al, 2017). In Colombia, this natural ecosystem covers 24.9% of its surface ; however, natural and anthropic factors, such as land use and land use change (LULUFC) exert high pressure on this ecosystem (Cárdenas-Burgos et al, 2019;Quintero et al, 2017).…”

High Andean forests are strategic ecosystems with high diversity of native and endemic plants; however, these natural ecosystems are affected by agricultural expansion. Knowledge on the propagation of native plants is essential to restore these environments. This research aimed to evaluate germination in the following native species: Viburnum triphyllum Kunt. (Caprifoliaceae), Oreopanax floribundum Kunth, (Araliaceae), Weinmannia tomentosa L.f. (Cunoniaceae), and Tournefortia fuliginosa Benth. (Boraginaceae) in Botana experimental farm of Universidad de Nariño. This study was conducted between October (2016) and February (2017). For each species, an unrestricted randomized split-plot design was established. The main plot included the substrates (S), and the sub-plots included the different pre-germination treatments (PM) with three repetitions. The results showed statistically differences in germination percentage among pre-germination treatments for O. floribundum. The highest germination percentage (42%) for this species was achieved with seed imbibition for 48 hours at 22°C. Moreover, W. tomentosa showed statistical differences for S and PM, with a germination percentage of 74% with imbibition for 48 h at 22°C and sand substrate. T. fuliginosa did not show relevant differences; however, it had a germination percentage of 47%. V. triphyllum did not germinate; therefore, further evaluations of pre-germination treatments should be required.

“…Por otro lado, el género Solanum perteneciente a la familia Solanaceae, posee más de 2300 especies en todo el mundo (Sheeba, 2010), las cuales son conocidas por presentar diversos tipos de actividad biológica, gracias a los compuestos que tienen este potencial. Solanum dolichosepalum (frutillo) es una planta de bosque húmedo montano bajo y montano alto ubicado en la Cordillera Central de Colombia (Cárdenas;Pérez, 2013;Marin-Ocampo;López-Zuluaga;Pérez-Cardenas;Isaza-Mejia, 2006). Además, es un arbusto nativo y escaso; presente en sitios abiertos y en suelos muy erosionados (Cárdenas-Burgos;Pacheco-Maldonado;Vanzela, 2016;González-M;López-Camacho, 2012).…”

“…En cuanto a su uso, las hojas y frutos son utilizados para ayudar a cicatrizar, eliminar piojos y tratar enfermedades renales; asimismo, es usado como inmunoestimulante, antiinflamatorio, antibacteriano y antifúngico (Cárdenas et al, 2013;Marin-Ocampo et al, 2006;Ramírez-Cárdenas;Isaza-Mejía;Martínez-Garzón, 2017;Martin-G.;Cárdenas;Pacheco;Cárdenas, Gómez, 2016). Sin embargo, S. dolichosepalum es una especie poco estudiada como agente antimicrobiano.…”

ResumenLas plantas pertenecientes al género Solanum son conocidas por su amplio espectro de actividad biológica. Por esto, el objetivo de este trabajo fue evaluar la acción antibacteriana de extractos etanólicos y metanólicos de Solanum dolichosepalum sobre las cepas bacterianas Staphylococcus aureus, Salmonella spp., Pseudomonas aeruginosa y Aeromonas hydrophila. Los extractos fueron obtenidos por extracción sólido-líquido en equipos Soxhlet, con posterior concentración por evaporación rotatoria. Para determinar la actividad antibacteriana se usó el método de difusión en disco, empleando agar Mueller Hinton, Cloranfenicol (sensidiscos de 30 mg) como control positivo, y los solventes de extracción como controles negativos. Los extractos metanólicos y etanólicos de S. dolichosepalum mostraron un leve efecto inhibitorio contra S. aureus, Salmonella spp., A. hydrophila y P. aeruginosa, pero no fue suficiente para considerarse significativo mostrando resistencia a los mismos. Para los dos tipos de extractos usados, el etanólico fue el más activo sobre S. aureus, Salmonella spp., A. hydrophila, y el metanólico frente a P. aeruginosa. AbstractThe plants belonging to the genus Solanum are known for their broad spectrum of biological activity. Therefore, the objective of this work was to evaluate the antibacterial activity of ethanolic and methanolic extracts of S. dolichosepalum against bacterial strains S. aureus, Salmonella spp, P. aeruginosa, and A. hydrophila. The methanolic and ethanolic extracts were obtained by solid-liquid extraction in soxhlet equipment, with subsequent concentration by rotary evaporation. To determine the antibacterial activity, the disc diffusion method was used, using Mueller Hinton agar, Chloramphenicol (30 mg sensitives) as a positive control, and extraction solvents as negative controls. The methanolic and ethanolic extracts of S. dolichosepalum showed a slight inhibitory effect against S. aureus, Salmonella spp, A. hydrophila, and P. aeruginosa, but it was not enough to be considered significant showing resistance to them. The two types of extracts used, ethanolic was the most active against S. aureus, Salmonella spp, A. hydrophila, and methanolic against P. aeruginosa.
