Antimicrobial activity of essential oils of Aloysia triphylla (L`Her.) Britton from different regions of Argentina

Essential oils are known to exert antimicrobial activity. Differences in the chemical composition of them influence this activity. This work intends to study the variability in the chemical composition and the antimicrobial activity of essential oils obtained from plants of A. triphylla collected from different regions of Argentina. Essential oils were obtained by hydrodistillation and analyzed with GC-MS. The antimicrobial studies were carried out by the paper disc diffusion method. The essential oils shared common components but presented differences in the quantity and quality of the rest of them. The essential oil from La Paz showed the highest citral/limonene relation and the best antimicrobial activity. Yeasts resulted to be the most sensitive microorganisms, followed by the Gram positive bacteria. Statistical analysis showed significative differences in the antimicrobial activity. The differences in the biological activity of each essential oil could be attributed to the quantity and quality of the terpenic composition.
