GC-MS Analysis and Antimicrobial Screening of Essential Oil from Lemongrass (Cymbopogon citratus)

Medicinal plants are source of a great economic value. Plant herbs are naturally gifted at the synthesis of medicinal compounds. The extraction and characterization of bioactive compounds from medicinal plants have resulted in the discovery of new drugs with high therapeutic value. Lemon grass was collected from administration gardens near Burjifartih west Khartoum, and was extracted for its oil by the hydro-distillation method approximately four hours. the extracted oil was analyzed by GC-MS and chemical constituents in the oil were identified, the major compounds in the oil were, citral (34.8%), neral (30.72%), β-myrecene (11.28%), geraniol (5.54%), 1,3,4-trimethyl 3-cyclohexene-1-Carboxaldehyde (2.20%), citonellol (1.34%). The compounds, D-Limonene (0.03%), Geranyl Acetate (0.57%) and Bicyclo [3.1.1] heptane-2-Carboxaldehyde-6,6-dimethyl (0.23%) were the minor compounds. antibacterial and antifungal activities of the oil were tested, all tested microorganisms were sensitive and no resistant was not observed, all growth inhibition zones occurred in the high activity level which is (>18mm).
