Chemical Constituents of the Essential Oil Extracted from Nicotiana tabacum Leaves

Gas Chromatography-Mass Spectrometric (GC-MS) was used to investigate the chemical constituents of the essential oil from fresh leaves of Nicotiana tabacum L. The result revealed thirty six (36) compounds representing 100% of the essential oil characterized from the leaves of Nicotiana tabacum L. The major constituents are 3, 7, 11, 15-Tetramethyl-2-hexadecen-1-ol 16.37%, P-xylene 12.37%, Cyclohexane 8.43%, Farnesol isomer a 3.08%, and 1-Naphthalenepropanol 3.08%.
