EVALUATION OF CHEMICAL CONSTITUENT OF CITRUS MEDICA LIMONUM LEAF ESSENTIAL OIL

In the present study Citrus medica limon u m leaves essential oil was e xtracted by hydro distillation and t he chemical constituent s were analyz ed by gas chromatography mass spectroscopy (GC - MS) and Fourier transform infrared (FTIR) spectroscopy . Eleven components were identified in the leaf o il by GC MS, 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, CH 3 C - H, C=O, H - C=O, C - H, N - H, CH 3 , CH 2 .
