Abstract

Microorganisms are becoming resistant to the commonly used chemical disinfectants. Thereby, these chemical products should now be replaced by natural ones. In this context, this research aimed to evaluate the disinfectant activity of the extract and decoction of Libidibia ferrea leaves in different surfaces. Thus, two forms of jucá leaf extraction (decoction and hydroalcoholic extraction) were tested through the diffusion disk technique from Kirby and Bauer, growth curve, acceptability test with the population, and surface test. Results showed sensibility to decoction of S. aureus and E. faecalis strains; however, for the extract, the strains that demonstrated sensibility were S. aureus, P. aeruginosa, Micrococcus spp. Corynebacterium spp., and S. Typhimurium in the diffusion disk test. A reduction of the bacterial charge throughout the growth curve was seen through the absorbance values after 24 hours to the strains of E. coli, E. feacalis, Micrococcus spp. and K. pneumoniae in the concentration of 100 mg/mL of the decoction and extract. Regarding the surfaces test, there was a reduction in the bacterial charge in all tested strains. Therefore, the L. ferrea may be used as an effective alternative disinfectant measure.
