Sumario: |
Medicinal plants are used more and more in our country for its therapeutic
properties, most of these not been evaluated scientifically, has been its use
ethnobotanical which has defined the therapeutic potential of each species. Croton
elegans Kunth (mosquera) is one of the species, on which there are no evaluations
biological activity or chemical identification, representing an opportunity to research
on this species, this work identifies qualitatively the phytochemicals present in the
plant groups and evaluated the antibacterial activity of Staphylococcus aureus ATCC
25923, Streptococcus mutans ATCC 25175, Streptococcus pneumoniae ATCC
49619, Streptococcus pyogenes ATCC 19615. Polar used extracts of chloroform and
hexane from the leaves of Croton elegans Kunth (mosquera), obtained by Soxhlet
method in concentrations of 25% and 50%. The phytochemistry of plant material
identification shows the presence of secondary metabolites: resins, amino acid,
Quinones, alkaloids, flavonoids, catechins. The antibacterial activity was evaluated
by diffusion on agar (Kirby-Bauer) method and the method in dilution in liquid,
without evidence of results of inhibition in none of the concentrations of the tested
pathogens, both by which research concludes by accepting the null hypothesis in
terms of antibacterial activity on the micro-organisms of study. |
