Abstract
This study aimed to analyze the chemical composition of fixed oils extracted from the fruits of Acrocomia aculeata, Syagrus cearensis and Attalea speciosa, in addition to evaluating their efficacy in combating resistant microorganisms, such as Escherichia coli and Staphylococcus aureus. The ripe fruits were collected in the region of Barbalha, Ceara , and the extracted oils were analyzed by gas chromatography and mass spectrometry (GC/MS) to identify the compounds present. The antibacterial activity was tested using the microdilution method in 96-well plates, evaluating the inhibition of bacterial growth at different concentrations of the oils. The chromatographic analysis of the fixed oils of Acrocomia aculeata, Attalea speciosa and Syagrus cearensis revealed the predominance of saturated fatty acids, with lauric acid being the most abundant (41.71% to 47.21%). Oleic and myristic acids were also significant, while stearic and linoleic acids appeared in smaller amounts. Attalea speciosa showed inhibition of 40.17% against Escherichia coli and 40.77% against Staphylococcus aureus (1000 μg/mL). Acrocomia aculeata inhibited 44.76% of S. aureus (1000 μg/mL), and Syagrus cearensis had moderate activity against E. coli.
