The extracted oil from Gundelia Tournefortii seeds, which belongs to Asteraceae
family and which is known as one of the medical herbal plants that is widely spread in the
Syrian environment, was isolated using soxhlet continuous extraction. It's ch
emical
composition was determined by GC/MS (Gas Chromatography – Mass Spectrometry). The
analysis led to identification of 20 components. The extracted oil was characterized by
high content of Linoleic Acid (52.9%), Palmitic Acid (20.1%) and Squalene (10.1%).
Flowers of Inula viscosa (L.) plant (Inula genus , Asteraceae family), locally known
as Taion, was collected from two different regions of Lattakia: the Jubt Barghal region (a
mountainous area), the Qaya region (a coastal area), and the essential o
il was extracted by
Hydrodistillation using the Cleveger apparatus , where the weight percentage of essential
oil stood at 1.26%,1.1% for both mountainous and coastal region ,respectively. The
Chemical composition of essential oil obtained from flowers of Inula viscosa (L.) was
analyzed by GC/MS .
The essential oil of the mountainous area contained 60 components, 58 components
of which were identified, that accounting for (97.98%) of total essential oil. The main
component controlling was:
7-methoxy-5-ethoxy-2,2-dimethyl-2H-chromene (43.43%)
The essential oil of the coastal region contained 33 components, 32 components of
which were identified, that accounting for (98.31%) of total essential oil. The main
components were:
Linalyl propionate (19.70%), Eugenol (15.11%), n-Eicosane (9.27%).
