ABSTRACT

The use of plants as an object of study in the area of concentration in environmental toxicology rekindled the importance of the use of bioassays that allow the evaluation of the real actions attributed to these plants, as well as the exposure of the population to the active principles that constitute such specimens. Bauhiniassp, a plant belonging to the family Leguminosae, commonly known as the "pata-de-vaca" (cow leg), is one of the 71 species of plant related in Renisus, since it is attributed to this genus actions hypoglycemic, diuretic, hypocholesterolemic and other disorders Still in research and discussion. As most of these disorders are related to dysfunctions associated with oxidative stress and cellular damage, the aim of the present study was to evaluate the antioxidant, antibacterial activities from aqueous extracts of leaves of Bauhinia blakeana. Leaves were collected, processed and extracted by infusion, which was used in three different strains of Escherichia coli by the disc diffusion method. A 0.9 % NaCl solution was used as the negative control. For antibacterial evaluation the positive control was attributed to antibiotics and in the antioxidant activity to stannous chloride and hydrogen peroxide. Assuming that B. blakeana is a hybrid of two other species of the genus, the results obtained did not corroborate all the results found in the literature, but such results contribute to the identification and qualification process.
