Resumo: | In last years, the increasing of the incidence of oxidative diseases and infections caused by multi-resistant pathogens to drugs has encouraged the study of natural products, especially those focused on research about phytochemical and therapeutic aspects on non-knowing plants, like the ferns. The aim of this study was to investigate the antimicrobial and antioxidant activity, the total amount of phenolic compounds and flavonoids from methanolic extracts obtained from the subterranean and aerial parts of species of the genus Blechnum from Atlantic Forest of Bahia - B. occidentale L. and B.serrulatum Rich. In the investigation of the antimicrobial activity of crude extracts the minimum inhibitory concentration (MIC) and minimum bactericidal/fungicide concentration (MBC/MFC) was determined. The micro-organisms tested were: Escherichia coli CCMB 261, Pseudomonas aeruginosa CCMB 268, Bacillus cereus CCMB 282, Staphylococcus aureus CCMB 262, Candida albicans CCMB 286 and Candida parapsilosis CCMB 288. In the antioxidant assay was used the scavenging stable radical 2,2-diphenyl-1-picryl-hydrazyl (DPPH) methodology. The levels of total phenolic compounds and flavonoids in the extracts were obtained by spectrophotometric methods using, in the first case, the Folin-Ciocalteau reagent and in the second, aluminum chloride. In the antimicrobial assay, all extracts inhibited the growth of, at least, four microrganisms tested, highlighting the extract of the aerial part of B. serrulatum, which inhibited five microrganisms and had the lowest MIC and MBC / MFC. In the antioxidant assay also the most active extract was one obtained from the aerial parts of B. serrulatum. All extracts showed phenolic compounds and flavonoids. With the extract of the aerial part of B. serrulatum, the percentage of antioxidant activity was proportional to the total phenolic quantity, but it was not observed the same association with the flavonoids quantity. The results of this study indicate the species of this study as possible targets in bioprospection of new antimicrobials and antioxidants agents. |

O objetivo desse trabalho foi investigar a atividade antimicrobiana, antioxidante e o conte?do de compostos fen?licos totais e flavon?ides de extratos metan?licos obtidos das partes a?rea e subterr?nea de esp?cies do g?nero Blechnum da Mata Atl?ntica da Bahia - B. occidentale L. e B. serrulatum Rich. Na investiga??o da atividade antimicrobiana dos extratos brutos a Concentra??o Inibit?ria M?nima (CIM) e a Concentra??o Bactericida/Fungicida M?nima (CBM/CFM) foram determinadas. Os micro-organismos testados foram: Escherichia coli CCMB 261, Pseudomonas aeruginosa CCMB 268, Bacillus cereus CCMB 282, Staphylococcus aureus CCMB 262, Candida albicans CCMB 286 e Candida parapsilosis CCMB 288. No ensaio antioxidante foi empregada a metodologia de seq?estro do radical est?vel 2,2-difenil-1-picrilhidrazila (DPPH). Os teores de compostos fen?licos totais e de flavon?ides nos extratos foram obtidos por m?todos espectrofotom?tricos empregando, no primeiro caso, o reativo de Folin Ciocalteau e, no segundo, o cloreto de alum?nio. No ensaio antimicrobiano, todos os extratos inibiram o crescimento de ao menos quatro micro-organismos testados, destacando-se o extrato da parte a?rea de B. serrulatum, que inibiu cinco micro-organismos e apresentou os menores valores de CIM e CBM/CFM. No ensaio antioxidante o extrato mais ativo tamb?m foi aquele obtido da parte a?rea de B. serrulatum. Todos os extratos apresentaram compostos fen?licos e flavon?ides. Com o extrato da parte a?rea de B. serrulatum, observou-se um percentual de atividade antioxidante proporcional ao conte?do fen?lico total, mas n?o foi observada a mesma associa??o com o conte?do de flavon?ides. Os resultados obtidos apontam as esp?cies desse estudo como poss?veis alvos na bioprospec??o de novos agentes antimicrobianos e antioxidantes.Submitted by Ricardo Cedraz Duque Moliterno (ricardo.moliterno@uefs.br) on 2020-05-15T22:49:01Z No. of bitstreams: 1 DISSERTA??O MESTRADO FERNANDA - VERS?O FINAL.pdf: 3288638 bytes, checksum: 911150f98ade1707c4761d92d2b33a71 (MD5)Made available in DSpace on 2020-05-15T22:49:01Z (GMT).
