Abstract

This study aimed chemical characterization and microbiological evaluation of extracts obtained from the waste of woods marketed in Paraná State: Peroba-Rosa (Aspidosperma sp.), Roxinho (Peltogyne sp.), Jatobá (Hymenaea sp.), Curupixá (Micropholis sp.), Itaúba (Mezilaurus sp.), Cedrilho (Erisma sp.) and Imbúia (Licaria sp.), whose botanical identifications were based on anatomical studies. The extracts were prepared with different solvents, analyzed by TLC and UV/VIS techniques, and tested against: Proteus mirabilis ATCC15290, Staphylococcus aureus ATCC25923, Escherichia coli ATCC25922, Enterobacter aerogenes ATCC13048, Micrococcus luteus ATCC9341, Klebsiella pneumoniae ATCC13883, Pseudomonas aeroginosa ATCC27853, Staphylococcus aureus, Streptococcus mutans and Bacillus cereus isolated from the clinic. The ethanol extract from Peroba-rosa containing alkaloids showed activity against P. mirabilis. Itaúba, Jatobá and Imbúia methanol extracts containing phenolics, and the Roxinho ethyl acetate extract containing terpenoids and phenolics were active against K. pneumoniae, M. luteus, E. coli, S. aureus and P. mirabilis. P. aeroginosa, S. mutans and E. aerogenes were resistant to the extracts.
