The lemongrass (Cymbopogon citratus L.) essential oil plays a vital role as an ingredient in differentfields due to aromatic, antibacterial properties and antifungal activity. In this study, essential oil oflemongrass was obtained using hydrodistillation method and evaluated for chemical compositionsand physico-chemical characteristics. The averaged physico-chemical parameters were determined asspecific gravity (0.8865 g/cm3), acid index (2.948), ester index (6.402) and refractive index (9.35).Moreover, the hydrodistillation process performance was achieved 0.29%. The composition of essentialoils was analyzed by GC-MS, revealing a total of 18 volatile constituents existing in the lemongrassoil. The major components were α-citral (40.838%), β-citral (28.494%), β-myrcene (16.654%),2,3-dehydro-1,8-cineole (2.264%) and geraniol (2.388%). The citral component accounts for highcontent (more than 70% of volume) of oil.
