ABSTRACT Abstract: In order to characterize the essential oils of leaves and inflorescences, water distilled volatile oils of hydroponically grown Ocimum basilicum L. were analyzed by GC/EI-MS. Fifty components were identified in the inflorescence and leaf essential oils of the basil plants, accounting for 98.8 and 99.9 % of the total quantified components respectively. Phenylpropanoids (37.7 % for the inflorescence vs. 58.3 % for the leaves) were the predominant class of oil cons- tituents, followed by sesquiterpenes (33.3 vs. 19.4 %) and monoterpenes (27.7
vs. 22.1 %). Of the monoterpenoid compounds, oxygenated monoterpenes (25.2 vs. 18.9 %) were the main subclass. Sesquiterpene hydrocarbons (25 vs. 15.9 %) were the main subclass of sesquiterpenoidal compounds. Methyl cha- vicol, a phenylpropane derivative, (37.2 vs. 56.7 %) was the principle com- ponent of both organ oils, with up to 38 and 57 % of the total identified components of the inflorescence and leaf essential oils, respectively. Linalool (21.1 vs. 13.1 %) was the second common major component followed by α- cadinol (6.1 vs. 3 %), germacrene D (6.1 vs. 2.7 %) and 1,8-cineole (2.4 vs. 3.5 %). There were significant quantitative but very small qualitative differences between the two oils. In total, considering the previous reports, it seems that essential oil composition of hydroponically grown O. basilicum L. had volatile constituents comparable with field grown counterparts, probably with potential applicability in the pharmaceutical and food industries.
