Fatty Acid Profile and Antimicrobial Activity of Oils Extracted from Seeds of Oleaginous Plant Species

Background: The in vitro antimicrobial effect of lipids has been studied and antimicrobial action of these lipids has been observed in various microbial groups. Objectives: The research studied the fatty acid profile and antimicrobial action of seed oil Acrocomia emensis, Attalea burretiana and Carpotroche brasiliensis against strains of Pseudomonas aeruginosa, Escherichia coli and Staphylococcus aureus. Materials and Methods: The analyzes were extracted and then hydrolysis and methylation were performed for later by Gas Chromatography coupled to a Mass Spectrometer. The determination of the antimicrobial action was determined by the agar diffusion method. Results: In species Acrocomia emensis and Attalea burretiana lauric acid was the most abundant fatty followed by myristic acid. In the oil of Carpotroche brasiliensis the hidnocarpic, chaumoogric and gorlic acids were in a greater concentration. The antimicrobial activity was observed in inhibition zones between 8-14 mm, so these oils can be made possible used as pharmaceutical adjuvants in antibiotic preparations.
