Abstract

Essential oils are one of the important natural products derived from plant for their various biological activities, however, the antimicrobial activities vary in potency and usage. Comparative antimicrobial activities of essential oils of lemon grass (Cymbopogon citrtus, and Orange (Citrus sinensis) peel against three bacterial species (Salmonella typhy, Pseudomonas aeruginesa, and Staphylococcus aureus) and two fungal species (Candida albicans, and Aspergillus niger). The essential oils were extracted by steam distillation. Antibacterial and antifungal activities were determined by paper disc diffusion technique and micro-dilution. The results showed both essential oils of lemon grass and orange peels exhibited strong antibacterial and antifungal activities against the test organisms with zones of inhibition ranging from 15.00mm to 28.00 mm. Comparison of the inhibitory activities of the two oils showed orange had lower effect of 15.60mm as against lemon grass 19.00mm at concentration of 20µ/ml against salmonella typhi. Inhibitory activities was 28.30mm highest on Staphylococcus aureus for orange peel and 28.00mm for lemon grass oil. The minimum inhibitory concentration (MIC) and minimum bactericidal (MBC) and minimum fungicidal concentration (MFC) indicated values20µl/ml and 10µ/ml against S.aureus respectively. The result demonstrated that both essential oils of lemon grass and orange have high potential antimicrobial activities that can be developed into potent drugs.
