title: Minimum antimicrobial inhibitory concentration of carnosol and of the ethanol extract from Lepichinia hastata (Lamiaceae).
abstract: The minimum inhibitory concentrations (MIC) of carnosol and of the ethanolic extract from the aerial part of Lepechinia hastata were determined against Streptococcus pyogenes, Bacillus subtilis, Staphylococcus aureus, S. epidermidis, S. aureus (2), S. aureus "A", and S. aureus "B", (strains "A" and "B" are resistant to penicillin and ampicillin), Escherichia coli, Enterobacter cloacae, Klebsiella pneumoniae, Salmonella typhimurium, Proteus vulgaris, and Pseudomonas aeruginosa and Candida albicans. Carnosol and the ethanol extract showed activity against gram (+) bacteria, but no activity against the yeast and the gram (-) bacteria.
