SummaryCordia dendata Poir, Heliotropium indicum Linn and Momordica charantia Linn are used for treatment of the most common human diseases and health disorders in folk medicine of the population from the northern Colombian coast. In this study, chemical composition and antibacterial activity of the ethanol extract and fractions from C. dentata, H. indicum and M. charantia were investigated. The chemical constituents of qualitative detection were examined by Thin Layer Chromatography (TLC). The antibacterial activity was determined by agar gel diffusion and broth microdilution method. The main identified compounds were flavonoids, cardiac glycosides, alkaloids, saponins, terpenoids, tannins and coumarins. The minimal inhibitory concentration (MIC) was 31.25 to 1000 g/mL for Gram-positive and Gram-negative bacteria, respectively. These results indicated that ethanol extract and fractions from C. dentata, H. indicum and M. charantia significantly inhibited the growth of standard strains. Potent antibacterial activities of C. dentata, H. indicum and M. charantia may be considered in future study, particularly against antibiotic-resistant cases.

Se realizó un inventario de las mariposas de Isla Grande, la isla más extensa del Archipiélago Islas del Rosario (Cartagena de Indias) en el mar Caribe colombiano, a partir de muestreos realizados entre agosto y noviembre de 2017, empleando redes entomológicas y trampas Van Someren-Rydon en fragmentos de bosque seco tropical, donde se ubicaron 13 transectos de 100 m x 10 m. Se registró un total de 129 individuos distribuidos en seis familias, 14 subfamilias y 25 especies. La presencia de Polygonus savigny (Hesperiidae) se confirma para el Caribe colombiano. La familia Nymphalidae fue la más representativa, por el contrario, las familias Lycaenidae, Riodinidae y Papilionidae presentaron la menor representatividad. Las especies se clasificaron a partir del número de individuos capturados, registrándose cinco especies abundantes, cuatro comunes, tres escasas y 13 raras. Se considera que la realización de muestreos en época seca y de transición permitirá ampliar el número de especies registradas para la isla. Estos resultados constituyen el primer listado de las mariposas de Isla Grande, información que constituye una línea de referencia para posteriores estudios.
