Purpose: To investigate and compare the essential oil composition of two
Grammosciadium
species
obtained by hydrodistillation
Methods: The essential oil of the aerial parts of two species was obtained by hydrodistillation and
analyzed by gas chromatography (GC) and gas chromatography - mass spectrometry (GC-MS).
Results: In
G. platycarpum
, twenty-seven compounds were identified representing 99.3 % of the total
oil. The major constituents of the oil were limonene (28.4 %), β-pinene (16.1 %), β-selinene (15.9 %), δ-
3-carene (11.2 %), α-farnesene (6.0 %) and p - cymene (4.7 %). The oil of
G. macrodon
contained
thirty-seven components representing 94.4 % of the total oil, with caryophyllene oxide (15.9 %),
germacrene - D (12.4 %), β-caryophyllene (11.5 %), δ-3 - carene (10.1 %) and cyclohexane (4.6 %) as
the main constituents.
Conclusion: The essential oil composition of
G. macrodon was analysed for the first time, the most
abundant constituents being caryophyllene oxide, and cyclohexane.
