Orbignya speciosa and Mauritia flexuosa are two native palm tree species found in Brazil. Their fruits are rich in edible fixed oils, which are used for many purposes in industry, such as in the manufacture of soaps, surfactants and margarines. The aim of this work was to characterize the chemical profiles and antioxidant properties of the methanol extracts obtained from the fruits of O.

- The study aimed to investigate the interactions between ethanol extracts of two plants, Amburana cearensis and Anadenanthera macrocarpa, and six antimicrobial drugs against resistant strains of Staphylococcus aureus and Escherichia coli.
- The antibacterial effectiveness was measured using the minimum inhibitory concentration (MIC) method, and a microdilution assay was conducted to explore interactions between the natural extracts and antibiotics.
- Notably, the combination of amikacin with Anadenanthera macrocarpa extract significantly improved its effectiveness against one E. coli strain, while β-lactam antibiotics generally did not show enhanced activity, and some interactions, like with ampicillin, were antagonistic.
