A atividade antimicrobiana de Calendula officinalis L. (Asteraceae) ja foi cientificamente comprovada em outros paises. O objetivo deste trabalho foi avaliar a atividade antibacteriana de C. officinalis cultivada no Parana - Brasil, nas condicoes de extracao etanolica 50%, com filtracao e particoes sucessivas com hexano, diclorometano, acetato de etila e butanol, frente a cepas Escherichia coli ATCC 25922, Pseudomonas aeruginosa ATCC 27853, Staphylococcus aureus ATCC 25923, Staphylococcus epidermidis ATCC 12228 e Bacillus cereus, pela tecnica da difusao em meio solido por cavidade e posteriormente pelo metodo de diluicao em placa. Os resultados demonstraram que algumas fracoes do extrato inibiram as bacterias gram-positivas, com atividade frente a Staphylococcus e Bacilos e inexiste em gram negativas, indicando que o principio ativo responsavel pela atividade antibacteriana observada possa ser isolado a partir das fracoes Hexânica e DCM nas condicoes de extracao propostas neste trabalho. Abstract The Calendula officinalis L. (Asteraceae) antimicrobial action has already been scientifically proved in other countries. The aim of this study was to assess the antibacterial action of the Callendula officinalis which is grown in Parana - Brasil, under extraction conditions at ethanol 50%, with filtration and successive partitions with hexane, dichloromethane, ethyl acetate and butane, contrasting with strains Escherichia coli ATCC 25922, Pseudomonas aeruginosa ATCC 27853, Staphylococcus aureus ATCC 25923, Staphylococcus epidermidis ATCC 12228 and Bacilus cereus, by the difusion technique in solid media by cavity and afterwards by the plaque dilution method. The results showed that some fractions of the extract inhibited the gram-prositive bacteria, with activity in contrast with Staphylococcus and Bacillus and non-existing in gram-negative, also indicating that the active ingredient responsible for the antibacterial action observed can be isolated from the Hexanic and DCM fractions under the extraction conditions proposed in this study.
