Chemical composition, antioxidant and antibacterial activities of essential oils from leaves and flowers of Eugenia klotzschiana Berg (Myrtaceae).
Many essential oils (EOs) of different plant species possess interesting antimicrobial effects on buccal bacteria and antioxidant properties. Eugenia klotzschiana Berg (pêra-do-cerrado, in Portuguese) is a species of Myrtaceae with restricted distribution in the Cerrado. The essential oils were extracted through the hydrodistillation technique using a modified Clevenger apparatus (2 hours) and ...
متن کاملChemical composition and acetylcholinesterase inhibitory activity of essential oils of Myrceugenia myrcioides (Cambess.) O. Berg and Eugenia riedeliana O. Berg, Myrtaceae
The chemical composition of volatile oils from two Myrtaceae species, Myrceugenia myrcioides and Eugenia riedeliana, both native from the Brazilian Atlantic Rain Forest, was analyzed by GC-MS. Acetylcholinesterase inhibitory activity was colorimetrically evaluated for these oils. For M. myrcioides, monoterpene hydrocarbons represented the major class in the volatile oil, with α-pinene as the mo...
متن کاملChemical and biological evaluation of essential oils from two species of Myrtaceae - Eugenia uniflora L. and Plinia trunciflora (O. Berg) Kausel.
The chemical composition and antimicrobial activity of essential oils obtained from leaves of two Myrtaceae species-Eugenia uniflora L. and Plinia trunciflora (O. Berg) Kausel-were determined. Analysis by GC/MS as well as determination of Kovatz indexes indicated atractylone (26.78%) and curzerene (17.96%) as major constituents of E. uniflora oil and α-cadinol (19.15%), apiole (11.15%) and cube...
متن کاملChloroplast DNA variation and phylogeography of Eugenia uniflora L. (Myrtaceae) in the Brazilian Atlantic forest
Introduction and objectives The Atlantic Forest (AF) is considered the second largest tropical forest in South America with high species richness and endemisms, harboring a large diversity of animals, plants and habitats types [1]. This biome covers an area of more than one million square kilometres along the Brazilian coast and extending to eastern Paraguay and northeastern Argentina [2]. AF i...
متن کاملPhytotoxic potential of young leaves from Blepharocalyx salicifolius (Kunth) O. Berg (Myrtaceae).
The loss of leaves by plant species found in the Cerrado (Brazilian savanna) is an energetically expensive process due to adverse environmental conditions and predation by herbivory. The mature leaves have adaptations which minimize these events. However, the young individuals lack these structures and produce high leaf concentrations of secondary metabolites as a form of protection. These comp...
