Abstract

The vegetal kingdom provides a great variety of compounds which are highly useful in human illnesses, especially those caused by microorganisms. One of the most relevant issues during the last decades is bacterial resistance, which is extremely serious due to difficulties in discovering new antibiotic agents. Current study evaluates the phytochemical profile by analyzing the antimicrobial and cytotoxic activity of the extracts of the plants Schinusterebinthifolia, Maytenusilicifolia Reissek, Tabebuia avellanedae, Anadenanthera colubrina (Vell.) Brenan. Plants´ extracts included tannins and alkaloids in their phytochemical compositions. T. avellanedae did not have any inhibitory activity to the microorganisms tested, whereas the other extracts tested presented inhibitory activity at different concentrations. The cytotoxicity test showed that T. avellanedae had high toxicity. The required antimicrobial activity may be found in several species of medicinal plants. However, the use of folk medicine plants should be scientifically assessed so that their main active agents and mechanisms may be characterized.
