| Sumario: | The search for new antibacterial substances has increased mainly due to higher bacterial resistance to the drugs commonly used forthe treatment of diverse diseases. Plants synthesize secondary compounds as a defense mechanism against adverse environmental conditions. These substances may act on the growth or development of some microorganisms. Most Asteraceae plants synthesize sesquiterpenic lactones. These compounds have been studied for bactericidal activity. The objective of this study was to evaluate the bactericidal action of the crude extract of two species of Asteraceae: Helianthus tuberosus and Smallanthus sonchifolius. Sensitivity tests were performed with the incorporation of the two plant crude extracts at different concentrations in agar followed by the inoculation of S. aureus and E. coli bacteria. The results demonstrated that both extracts showed total inhibition activity over the growth of S. aureus and partial inhibition activity over the growth of E. coli. |
