【 摘 要 】

The essential oils are a potential alternative to the control of phytopathogenic bacteria. The aims of this work to determine the chemical composition of the essential oil of Piper hispidum Sw. and to established it´s antibacterial activity against Xanthomonas albilineans (Ashby) Dowson and Xanthomonas campestris pv. campestris (Pammel) Dowson. The composition of the leaves essential oil of this plant, obtained by hydrodistillation in a Clevenger-type apparatus, was researched by Gas Chromatography- Mass Spectrometry (GC/MS). The antibacterial effect of the essential oil was evaluated using the agar diffusion method. The essential oil (yield 0,17%) is a complex oil that have trans- a- bisabolene (11,28%) as the principal component and there are others like: b-pinene (8,2%), a-pinene (4,76%), allo-aromadendrene (4,92%), (-) spatulenol (3,65%) and L-linalool (3,61%). The oil shown a weak antibacterial activity against X. campestris pv. campestris and strong against X. albilineans, for that it is may consider as a candidate for the management of this last bacterium.
