    ABSTRACT
    For the first time in Algeria, the quality and variability of the chemical composition of the essential oil isolated from the aerial parts of Lobularia maritima (L.) Desv. (Brassicales Brassicaceae) were studied in two ecologically different regions of Western Algeria. The yields obtained by hydrodistillation are 0.11% for the region of Tessala (wilaya of Sidi Bel Abbes), 0.19% for Beni-Saf (wilaya of Ain-Temouchent). Analysis by GC and GC/MS allowed us to identify 62 compounds in the essential oil from the Beni-Saf region and 54 in that of Tessala. The majority compounds in two regions show quantitative variability and are, respectively, linalol (24.78%; 26.95%), eucalyptol (9.12%; 11.57%), linalyl acetate (18.90%; 20.85%), cis-dihydro-terpinyl acetate (5.38% ; 9.73%), estragole (4.26%; 3.99%), α-terpineol (3.39%; 4.48%), geranyl formate (1.93%; 2.21%), terpineu, 4-o1 acetate (1.88%; 2.32%), ß-myrcene (1.84%; 1.89%), ß-pinene (1.24%; 1.05%) and e-ß-ocimene (1.16%; 1.94%).
