“…Desta forma, a presença de fitocomplexos em extratos brutos de plantas pode estar relaciona a ação antimicrobiana uma vez que o sinergismo entre os constituintes pode demonstrar efetividade maior contra os microrganismos testados se comparados a outros tipos de extratos (Arias et al, 2004;Simões et al, 2004).…”

RESUMO:As doenças transmitidas por alimentos ocorrem principalmente devido à ingestão de alimentos contaminados por microrganismos patogênicos, dentre eles a Escherichia coli e Listeria monocytogenes. Uma das alternativas estudadas para minimizar a contaminação de alimentos é o emprego de plantas, ou seus extratos, como agentes antimicrobianos de origem natural em produtos alimentícios. Desta forma o objetivo do presente estudo é fornecer dados científicos a respeito de duas plantas nativas do RS ainda não estudadas, Eugenia anomala e Psidium salutare, visando potencial emprego como agente antimicrobiano natural em alimentos. Para tanto, avaliou-se a atividade antimicrobiana de extratos de E. anomala e P. salutare contra E. coli e L. monocytogenes através da determinação da concentração inibitória mínima (CIM) pelo método de microdiluição em caldo, a capacidade antioxidante dos extratos por meio do método de redução do radical DPPH e a citotoxicidade in vitro empregando células CHO-K1. Os resultados obtidos mostraram que os extratos de acetato de etila e etanólico de ambas as espécies possuem ação antioxidante muito alta, de 94,08% e 93,86%, respectivamente. Apenas o extrato hexânico de P. salutare apresentou ação antimicrobiana moderada (CIM = 312,5 µg/mL). Todos os extratos apresentaram ação citotóxica sendo que os maiores percentuais foram do extrato clorofórmico de E. anomala (77,05%) e hexânico de P. salutare (76,79%), na concentração de 100 µg/mL. Assim, o presente estudo demonstrou que as espécies vegetais estudadas apresentam potencial para emprego como agente antimicrobiano destes microrganismos.Palavras-chave: Concentração Inibitória Mínima, Citotoxicidade in vitro, Atividade Antioxidante.ABSTRACT: Evaluation of the antimicrobial activity of extracts of Eugenia anomala and Psidium salutare (Myrtaceae) against the Escherichia coli and Listeria monocytogenes. The foodborne diseases occur mainly due to the ingestion of food contaminated by pathogenic microorganisms, including Escherichia coli and Listeria monocytogenes. One of the alternatives studied to minimize contamination of food is the use of plants or their extracts as antimicrobial agents naturally occurring in food products. The objective of this study is to provide scientific data on two native plants of RS have not studied Eugenia anomala and Psidium salutare for a potential use as a natural antimicrobial agent in food. To this end, we evaluated the antimicrobial activity of extracts of E. anomala and P. salutare against E. coli and L. monocytogenes by determining the minimum inhibitory concentration (MIC) by the broth microdilution method, the antioxidant capacity of the extract for means DPPH radical reduction method and in vitro cytotoxicity using CHO-K1 cells. The results showed that the ethyl acetate and ethanolic extracts of both species have very high antioxidant activity, of 94.08% and 93.86%, respectively. Only the hexane extract of P. salutare showed a moderate antimicrobial activity (MIC = 312.5 mg/mL). Moreover, all extracts showed ...

“…18,000 species distributed in more than 650 genera (Doyle et al, 1996), and they are classified into three different subfamilies: Caesalpinioideae, Papilionoideae and Mimosoideae. Although different biological activities have been demonstrated in the saline extract of members from the genus Acacia (Hung et al, 1993;Popoca et al, 1998;Arias et al, 2004), an important genus from Mimosoideae subfamily, the isolation and characterization of protease inhibitors were only described in a small number of its species, e.g. Acacia elata (Kortt and Jermyn, 1981), Acacia sieberana (Joubert, 1983) and Acacia confusa (Lin et al, 1991).…”

“…This is the first report on antibacterial activity of E. bungei Boiss against oral and skin pathogens. The ethanolic extracts show better antibacterial activity than aqueous (Arias et al, 2004). In this study, the growth of S. pyogenes and S. aureus was remarkably inhibited by the ethanolic extract of the three plants.…”

The aim of this study is to examine the antibacterial activity of plant extracts. Both broth dilution and disc diffusion methods were used to assess the antibacterial activity of these extracts against skin and oral pathogens. Eryngium caucaseum Trautv, Eryngium bungei Boiss and Adiantum capillus-veneris have shown antibacterial activity against Streptococcus pyogenes, Streptococcus mutans, Staphylococcus aureus and Streptococcus sanguis. E. caucaseum Trautv showed the highest inhibition zone (> 30 mm) against S. pyogenes. The growth of S. pyogenes was remarkably inhibited by the ethanolic extract of the three plant extracts.
