Abstract: Cymbopogon citrates (DC.) Stapf is an important and oldest species of Cymbopogon grass belonging to the family of Poaceae and commonly called western Indian lemongrass or lemongrass. The quality of lemongrass oil is determined by the content of Citral, an isomer of geranial (40-62%) and neral aldehyde (25-38%) responsible for the lemon odor. Other major components include in the essential oil include β-myrcene and Geraniol. The oil of C. citratus is known to posess varied biological activities. During the present investigation, the essential oil of C. citratus oil were fractionated into terpene-less and terpene-containing parts and investigated for antioxidant and antimicrobial activities. The in vitro antioxidant and ROS radical scavenging activity of the essential oil were evaluated by DPPH assay. The antimicrobial property of the pathogenic strains like Enterococcus faecalis, Staphylococcus aureus, Shigella dysenteriae, Salmonella typhii, Trichophyton rubrum and Cryptococcus neoformans were tested against the essential oil. The present investigation highlights the significance of C. citratus essential oil and their fractions as antimicrobial and antioxidant agent.
