Composition and antibacterial activity of the essential oil of Ruta chalepensis subsp.angustifolia from Algeria

摘要

The essential oil obtained by hydrodistillation of aerial parts of Ruta chalepensis subsp. angustifolia (Rutaceae) was analyzed by GC and GC/MS. 16 compounds were characterized representing 99.99% of the essential oil with 2- acetoxytetradecane (58.44%), 2-acetoxytridecane (19.07%) and 2-tridecanone (6.39%) as major components. The antibacterial activity of the essential oil was tested against 5 gram-positive and 4 gram-negative bacteria by the use of the disc diffusion method
