【 摘 要 】

The essential oil of Ruta chalepensis L, herb belonging to Rutaceae family, is useful in perfumery, for flavoring and has insecticidal activity. Its composition depends on the specific geobotanical conditions, and several chemiotypes has been described. The aim of this work was to establish the potential of the essential oil obtained from R. chalepensis as a candidate for the development of new antibacterials in the management of plant pathogens. The essential oil was obtained by hydrodistillation with a Clevenger equipment; the yield determined and its chemical composition investigated by GC/MS. The antibacterial assessment was conducted using the agar diffusion technique. In the composition of the essential oil of rue (yield of 0.3 % (v/w)), aliphatic ketones were predominant; 2-undecanone (34.88%) and 2-nonanone (25.23%) showed the higher relative abundance. R. chalepensis essence inhibited growth of Xanthomonas albilineans (Ashby) Dowson and Clavibacter michiganensis subsp. michiganensis (Smith) Davis et al. The antibacterial effect suggests that this essence can provide the basis for future development of new antimicrobials for pest management in sugar cane and tomato.
