abstract

  • In this study, the antibacterial activity of plants extracts traditionally used in disinfection of wound was evaluated. Acalypha monostachya, Cucurbita foetidissima, Gaura coccinea, Heterotheca subaxillaris and Sphaeralcea angustifolia extracts were tested against Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus strains. Aqueous and ethanolic extracts were prepared and the minimum bactericide concentrations (MBC) of these extracts were established. The antimicrobial activity was evaluated by Mueller Hinton diffusion agar technique. The dilution technique in Mueller-Hinton broth was used to determine the MBC. The best treatment against P. aeruginosa was the ethanol extract of A. monostachya with a MBC of 46.88 mg/mL, and for S. aureus the ethanol extract of H. subaxillaris with a MBC of 18.75 mg/mL. Only the ethanol extract of A. monostachya had an effect on E. coli, with a MBC higher than 125 mg/mL of dry plant.
