Abstract in Portuguese
Nesse estudo, foram avaliados os óleos voláteis de Porcelia macrocarpa (Warm) R. E. Fries e Rollinia sericea (R. E. Fries) R. E. Fries com relação a sua composição ao longo das estações anuais e sua atividade antimicrobiana e anticolinesterase. Entre os componentes majoritários foram identificados apenas sesquiterpenos em ambas as espécies, bicicloelemeno (7%), biciclogermacreno (10%), germacreno-D (15%) e espatulenol (15%) para a P. macrocarpa e, α-muurolol (5%), Z-nerolidol (6%), bicicloelemeno (7%), germacreno-D (10%), biciclogermacreno (10%), β-cariofileno (11 %) e β-elemeno (12%) para R. sericea, não apresentando variação sazonal significativa. Os testes antimicrobianos foram realizados com bactérias Gram--positivas e negativas e com fungos filamentosos e leveduriformes. Os resultados indicaram que os óleos testados apresentam um melhor potencial antifúngico do que antibacteriano quando testado na dose de 3,125 µL/mL e não apresentaram potencial para o desenvolvimento de novos fármacos para o tratamento da doença de Alzheimer.

Abstract in English
In this study, the volatile oils from Porcelia macrocarpa(Warm) R.E.Fr. and Rollinia sericea (R.E.Fr.) R.E.Fr. were analyzed for the seasonal variation in their chemical composition and their antimicrobial and anticholinesterase activity. The major components consisted only of sesquiterpenes in both species, bicycloelemene (7%), bicyclogermacrene (10%), germacrene-D (15%) and sphatulenol (15%) to P. macrocarpa and, α-muurolol (5%), Z-nerolidol (6%), bicycloelemene (7%), germacrene-D (10%), bicyclogermacrene (10%), β-caryophyllene (11 %) e β-elemene (12%) to R. sericea and no significant seasonal variation could be detected. The antimicrobial assays were performed with Gram-positive and negative bacteria, filamentous fungi and yeasts. The results indicated that the tested oils presented a better antifungal potential than antibacterial, when done test in the dose of 3,125 µL/mL. These oils could also not be considered as potential targets for the development of new drugs for the Alzheimer's treatment.
