dc.description.abstractThe leaves of Hyptis ovalifolia Benth. (Lamiaceae) were subjected to hydrodistillation and the resulting volatiles were investigated by GC/MS. The main constituent representing 60% of the essential oil was isolated by column chromatography and identified by spectroscopic methods as (R)-6-[(Z)-1-heptenyl]-5,6-dihydro-2H-pyran-2-one (1). This compound showed strong in vitro activity against four dermatophyte fungi Microsporum canis, Microsporum gypseum, Tricophyton mentagrophytes, and Tricophyton rubrum (a total of 60 strains) with a minimal inhibitory concentration observed in the range of 125-7.8 μg mL-1.pt_BR
dc.description.resumoAs folhas de Hyptis ovalifolia Benth. (Lamiaceae) foram submetidas à hidrodestilação e a fração volátil foi investigada por CG/EM. O componente principal, (R)-6-[(Z)-1-heptenila]-5,6-diidro-2Hpiranona (1), representando 60% do óleo essencial, foi isolado por cromatografia em coluna e identificado por métodos espectroscópicos. O composto mostrou atividade in vitro contra 4 espécies (60 isolados clínicos) dos dermatófitos: Microsporum canis, Microsporum gypseum, Tricophyton mentagrophytes e Tricophyton rubrum com concentração inibitória mínima variando de 125-7,8 μg mL-1.pt_BR
