Abstract

The hydro-distilled essential oil of Excocaria acerifolia has been examined by means of gas chromatography-mass spectrometry (GCMS). The oil constituents were identified according to their mass spectra and their relative retention indices determined on a non-polar stationary phase capillary column. Fifty-seven constituents have been identified representing 93.37% of the total oil. The main compounds in major amounts were Isopropyl isothiocyanate (14.03%), (E)- Caryophyllen (11.65%), Benzyl isothiocyanate (9.32%), 1, 3, 8- paramenthatriene (6.61%), the compound in trace or in minor amount were n-hexanol (0.06%), 2-Ethyl-5-methyl tetrahydrofuran (0.06%), the oil was found rich in oxygenated mono and sesquiterpene hydrocarbons.
