Abstract:		"The essential oil of aerial parts of Ruta montana L. growing in the Oran region in the west of Algeria was obtained by hydrodistillation with a 1.63% yield on a dry weight basis. Gas chromatography (GC) and GC/mass spectrometry (MS) analyses were carried out to identify the chemical composition of R. montana essential oil. Moreover, spectrophotometric analyses were employed to highlight the scavenger capacity of this oil using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) test. Twenty compounds were identified by GC and CG/MS analyses, and the bulk of the compounds of the oil were undecan-2-one (32.8%), nonan-2-one (29.5%), nonanol-2-acetate (18.2%), and psoralen (3.5%). The results obtained using the DPPH test show that R. montana essential oil possesses antiradical activity in a concentration-dependent manner. Thus, a linear correlation (correlation coefficient R(2) = 0.971, P < .001) was found between the reduction of DPPH stable free radical and the concentration of R. montana essential oil"
