Piper gaudichaudianum Kunth: Seasonal Characterization of the Essential Oil Chemical Composition of Leaves and Reproductive Organs
Disinfecting capacity of essential oil of Thymus pulegioides L. (lamiaceae) chemotypes against phytopathogenic Pseudomonas species
The antibacterial activity of essential oils of T. pulegioides chemotypes — geraniol/geranial/neral (G/G/N), thymol (T) and linalool (L) — was studied against the seven phytopathogenic Pseudomonas species isolated from vegetables. The chemotypes were defined according to their main essential oil components: geraniol, thymol and linalool. The results showed that the essential oil of T chemotype had the strongest anti-Pseudomonas activity: it inhibited the growth of all investigated bacteria up to even 84.4% in comparison with controls. The essential oils of L chemotype inhibited the growth of bacteria less than T chemotype, and G/G/N chemotype proved to be the least effective. These differences of anti-Pseudomonas activity depend on the different chemical composition of essential oils of investigated T. pulegioides chemotypes
