The aims of this study were to investigate the chemical constituents of the hydrodistilled oil and n- hexane extract of L. inermis leaves. The essential oil of L. inermis leaves was analyzed using GC-MS and revealed the presence of twenty eight components. Nine components comprising 80.6% of the total oil have been identified by MS, spectral data and by comparison with literature. According to the GC-MS results, eugenol, hexadecanoic acid, phytol, α-terpineol and etherphenylvinyl were the major components of the oil. Bisabolene was isolated from n- hexane extract and its structure was elucidated by NMR technique.
