Resumo: | Dematiaceous moulds are pathogen microorganisms able to act as etiological agents of mycoses with different degrees of severity. This study evaluated the effectiveness of Cinnamomum zeylanicum Blume essential oil and beta-pinene in inhibiting the growth of various strains of dematiaceous moulds (Alternaria brassicola, Cladosporium herbarium, C. resinae, C. cladosporioides, Chaetomum globosum, Curvularia sp., Fonsecaea compacta, Piedraia hortae). Antimicrobial assays were led by determining the Minimum Inhibitory Concentration-MIC using the solid medium diffusion procedure and observing the interference of the MIC values on the mould radial mycelial growth along 14 days. MIC values found to C. zeylanicum essential oil oscillated between 63 and 125 µL/mL. beta-pinene showed MIC value of 125 µL/mL for the most mould strains, however C. resinae and C. globosum were resistant to it in all assayed concentrations. MIC values found to C. zeylanicum essential oil and beta-pinene presented intense fungicidal effect noted by a total inhibition of the mycelial growth of C. cladosporioides and F. compacta along 14 days of exposure. These results showed the intense antimould potential of C. zeylanicum essential oil and beta-pinene which could be regarded in a rational use in pharmaceutical formulations used to treat some mycoses, particularly, those caused by dematiaceous moulds.
