In the present study Citrus medica limonum leaves essential oil was extracted by hydro distillation and the chemical constituents were analyzed by gas chromatography mass spectroscopy (GC-MS) and Fourier transform infrared (FTIR) spectroscopy. Eleven components were identified in the leaf oil by GCMS, the constituents are dominated by citronellal (29.31 %), limonene (17.59 %), (E)-citral (12.71 %), 1, 6-octadien-3-ol, 3, 7-dimethyl (10.91 %). FTIR identified the functional groups of the oil as C-I, C-H, =C-O-C, C-O, CH3C-H, C=O, H-C=O, C-H, N-H, CH3, CH2.
