Morphogenetic, Ontogenetic and Diurnal Variability in Content And Constituents of Bitter Fennel (Foeniculum vulgare Miller var. vulgare) Essential Oil
Abstract
The objective of this study was to
determine morphogenetic, ontogenetic and diurnal variability in content and
constituents of bitter fennel essential oil. Essential oils of various plant
organs (leaf, root-bulb-stalk, flower and seed) of bitter fennel harvested at
pre-, full- and post-flowering stages at different times (9 am, 1 and 5pm) were
extracted by hydro distillation and analyzed by gas chromatography and mass
spectrometry. Essential oil content differed significantly based on plant organ
and growing stage, increasing in the order of leaf < flower <seed, with a nearly seven-fold
increase occurring in seed essential oil as compared to that of leaf. Essential oil content increased from 1.68% at pre-flowering
to 2.18% at full-flowering but decreased sharply to 0.81% at post-flowering. Trans-anethole
was found to be the most prominent compound in all esssential oils, with
decreasing order of seed > flower > root-bulb-stalk > leaf essential
oil. Alpha-pinene, α–phellandrene, limonene and fenchone were the other major components,
varying significantly with plant growth stages and organs. The present study
reveals that the content and constituents of essential oil of bitter fennel
from Turkey are predominantly dependent on ontogenetical phase and plant organ.
