Efecto antibacteriano del extracto metanólico de Salix babylonica sobre bacterias de importancia en salud pública
Palavras-chave:
Salix babylonicaResumo
O uso excessivo de antimicrobianos tem gerado resistência dos microrganismos a estes, têm sido buscadas alternativas eficazes no tratamento de doenças causadas por microrganismos resistentes ou multirresistentes a antibióticos, dentre essas alternativas estão as plantas, que devido ao seu conteúdo composto de efeitos colaterais têm atividade antibacteriana. O objetivo do presente estudo foi caracterizar e determinar a atividade antibacteriana do extrato metanólico de Salix babylonica (SB) em bactérias de importância para a saúde pública. Para obtenção do extrato, foi utilizada a técnica de maceração, caracterização química qualitativa e quantitativa por cromatografia gasosa. Para determinar a atividade antibacteriana, foram determinadas a Concentração Inibitória Mínima (CIM) e a Concentração Bactericida Mínima (CBM) e a caracterização do extrato permitiu a identificação de compostos fenólicos, cumarinas, lactonas, flavonóis, quinonas, saponinas, triterpenos e compostos esteróides, além de compostos fenólicos. Timol (0,5319 mg/ml) e Carvacrol (0,4158 mg/ml). Com relação à atividade antibacteriana, a melhor atividade foi apresentada contra o Bacillus subtillis (CIM: 12,5 mg/mL e CBM: 25 mg/mL), Listeria monocytogenes e Staphylococcus aureus (CIM: 25 mg/mL e CBM: 50 mg/mL). Conclui-se que o extrato metanólico de SB pode ser uma alternativa para o tratamento de doenças causadas por bactérias
resistentes a antibióticos ou multiresistentes.
