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 constituents, 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 %) possessed the
main subclass of sesquiterpenoidal compounds as well. Methyl chavicol, a
phenylpropane derivative, (37.2 % vs. 56.7 %) was the principle component 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.
