Antimicrobial activity of Syagrus oleracea and Mauritia vinifera fruits

Palmae species are very interesting by the chemical and pharmacological points of view. Two species belonging to this family were chosen to initiate the chemical and pharmacological approach of their fruits: Syagrus oleracea (Martius) Beccari and Mauritia vinifera Martius, known in Brazil as Guariroba and Buriti, respectively. Those palm species can be found in several regions of Brazil, especially at the northeast and southeast of the country. They have been used in folk medicine to treat some diseases, however no toxicological and pharmacological studies have been done so far. For the two studied fruits, the antimicrobial activity tests were carried out by broth microdilution methodology. The objective of this work was to contribute for the pharmacological study of palm species, evaluating the antimicrobial activity of the extracts obtained from the fruits of S. oleracea and M. vinifera. The assays evaluated ethanol extracts of the epicarp/mesocarp of S. oleracea and epicarp/mesocarp of M. vinifera; hexane extract of the endosperm of S. oleracea; hexane and ethyl acetate fractions of the epicarp/mesocarp of S. oleracea, epicarp/mesocarp of M. vinifera and mesocarp/endocarp of M. vinifera. The lipophilic extracts of S. oleracea obtained the best results for the species. For M. vinifera, the lipophilic partitions have shown a high inhibitory percentage for S. aureus.
