In vitro evaluation of the antibacterial effect of Bidens pilosa, Lantana camara, Schinus molle and Silybum marianum
medicine is the bacterial resistance to the anti-bacterial treatments. Against this background the search of new active principles with anti-bacterial activity has been stimulated, reason why the objective of this work was to determine the anti-bacterial properties of four vegetal species, collected in the city of Tunja (Boyacá). Etanólicos extracts from dry leaves of Bidens pilosa, Lantana camara, Schinus molle and Silybum marianum were prepared and submitted to a microbiologic in vitro test, to establish their anti-bacterial activity, their minimal inhibiting and bactericidal concentrations, in response to Staphylococcus aureus, Escherichia coli and Pseudomona aeruginosa. All activities were compared to a standard medicine, cloranfenicol or gentamicina. The extracts showed activity against S. aureus. B. pilosa exhibited the best activity, L. camara, S. molle and S. marianum, showed moderate capacity to inhibit S. aureus growth. This study demonstrated that the selected plants have anti-bacterial activity against S. aureus.
