The leaf essential oil of Eucalyptus citriodora Hook belonging to the family Myrtaceae was analysed by GC-MS. The essential oil was obtained by hydrodistillation in yield of 3.5% (v/w). Twenty-nine different components accounting for 100% of the total volatile oils were identified. Citronellal (46.87%) was the predominant monoterpene constituent, followed by isopulegol (7.68%), citronellol (7.47%), 3-tetradecanol (4.98%) and citronellic acid (4.31%). 2D NMR analysis of the essential oil also identified citronellal as the major constituent. Methyleugenol (0.38%), geraniol (0.35 %), and geranyl acetate (0.35%) were identified as in minor quantities.
