Se realizó un análisis fitoquímico preliminar y un estudio de la letalidad sobre larvas de A. salina y toxicidad en Daphnia magna, de doce extractos etanólicos obtenidos de diez plantas utilizadas por algunas comunidades indígenas y campesinas de Colombia. Se encontró que todas poseen varios grupos de metabolitos secundarios y que la mayoría de los extractos, presentaron una alta toxicidad frente a los organismos de prueba, evidenciándose de esta forma la actividad biológica de las especies estudiadas y la posible correlación de las mismas con su uso en la medicina tradicional.
It was accomplished a Preliminary phytochemicals screening and a study of the Artemia salina (brine shrimp) lethality as well as Daphnia magna toxicity of twelve ethanolic extracts obtained of ten plants used by some indigenous communities and peasantes from Colombia. It was found that all possess several groups of secondary metabolites and most of the extracts, presented a high toxicity as compared to the test organisms, being evidenced in this way the biological activity of the studied species and the possible relation of the same with its use in the traditional medicine.
