Resumo

Este estudo objetivou identificar e quantificar os constituintes quí­­micos e avaliar a atividade antimicrobiana in vitro dos óleos essenciais de capim limão (Cymbopogum flexuosus - OECF) e manjericão (Ocimum basilicum - OEOB) frente a 24 isolados de Aeromonas spp. Os componentes majoritários de OECF foram o α-citral (50,13%) e í­Å¸-citral (40,31%), enquanto que de OEOB foram o linalol (53,35%) e eucaliptol (11,49%). OECF demonstrou atividade inibitória elevada (â"°¥ 195,31 µg mL-1), enquanto que OEOB apresentou atividade inibitória moderada (â"°¥ 781,25 µg mL-1) para Aeromonas spp. Ambos os óleos essenciais têm potencial para aplicação como agentes antimicrobianos, principalmente OECF.
