Abstract:

The in vitro antimicrobial activity of the essential oil isolated from the aerial parts of Cymbopogon Olivieri (Boiss.) Bor, an aromatic grass of Iran was tested against three Gram-negative and four Gram-positive bacteria and also three fungi. The results of the bioassays showed that the oil has a remarkable antimicrobial activity. Bacillus subtilis and Candida albicans were more sensitive to the oil than other microorganisms with inhibition zones of 20 mm and MIC values of 3.75 mg/ml and 2.5 mg/ml, respectively. The Gram-negative bacteria, Pseudomonas aeruginosa was resistant and Klebsiella pneumoniae showed less sensitivity to the oil with MIC value of >15 mg/ml. GC-MS analysis of the oil confirmed the determination of 40 compounds representing 95.0% of the oil. The main identified constituent was piperitone (48.9%).
