RESUMO

Introducción: Solanum dolichosepalum Bitter, llamada comúnmente frutillo, es tradicionalmente usada en Colombia como antibacteriano, antiinflamatorio, cicatrizante y en enfermedades renales. La escasa información en bases de datos sobre la planta en estudio no permitió referenciar un mayor número de artículos actuales. Objetivo: evaluar la actividad antibacteriana de extractos obtenidos del fruto de S. dolichosepalum y realizar un estudio fitoquímico preliminar. Método: la actividad antimicrobiana fue evaluada a partir de cuatro fracciones (F) obtenidas del extracto etanólico de los frutos secos deS. dolichosepalum frente a cepas deEscherichia coli, Staphylococcus aureus y Pseudomona aeruginosa por el método de Kirby-Bauer. La primera fracción se sometió a cromatografía en columna y a sus fracciones se les evaluó la concentración inhibitoria mínima (MIC) por el método de microdilución. Los metabolitos responsables de la actividad antimicrobiana...(AU)


Introduction: Solanum dolichosepalum Bitter, commonly known as frutillo, has been traditionally used in Colombia as antibacterial, antiinflammatory and cicatrizant, and to treat renal disease. Due to the scant information about the study plant contained in databases, it was not possible to reference a larger number of current papers. Objective: Evaluate the antibacterial activity of extracts obtained from the fruit of S. dolichosepalum and conduct a preliminary phytochemical study. Method: The Kirby-Bauer method was applied to four fractions (F) obtained from the ethanolic extract of dry fruits of S. dolichosepalum to evaluate antimicrobial activity against strains ofEscherichia coli, Staphylococcus aureus and Pseudomona aeruginosa. The first fraction underwent column chromatography and its fractions were tested for minimum inhibitory concentration (MIC) using the microdilution method. Metabolites responsible for antimicrobial activity were identified by thin layer chromatography on silica gel plates (MERCK) with an ultraviolet lamp (365 nm). Finally, a phytochemical study was conducted of the ethanolic extract of the fruits to determine the presence of bioactive metabolites.Results: Phytochemical testing of the ethanolic extract revealed the presence of alkaloids, steroids and/or free...(AU)
