تم فصل الزيت من بذور نبات السلبين Gundelia Tournefortii , الذي ينتمي إلى العائلة النباتية النجمية (Asteraceae) و الذي يعد من النباتات العشبية الطبية المنتشرة بشكل واسع في البيئة السورية, بطريقة الاستخلاص المستمر بالمذيبات باستخدام جهاز سوكسليت. تم تحديد التركيب الكيميائي للزيت المستخلص باستخدام تقنية الكرماتوغرافيا الغازية المرتبطة بمطيافية الكتلة GC/MS . و أدى التحليل إلى التعرف على 20 مركب و تميز الزيت المستخلص بالتركيز العالي لكل من المركبات التالية: حمض اللينوليك (52.9%), حمض البالميتيك (20.1%) و السكوالين (10.1%).
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 chemical 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%).

Due to the economical and medical importance of the Capparisspinosa plant and the
wide distribution of this plant in the Syria environment, it was thought that a study of the
composition of Essential Oil extracted from this plant.
The Capparisspin
osa Essential Oil was extracted and purified components wher
studied by GC-Mass spectrometry.
The Oil was obtained by steam distillation (Clevegerexractor) and by solvent n-
Hexane. Components have been found which was about (98.9 %) from the total of
essential oil.
The major components were determined by steam distillation which were the
following:Palmitic acid (21.12%), Hexatriacontane (15.87%), n-Heneicosane (10.96%),
Pentatriacontane (9.92%), Hexahydrofarnesyl acetone (8.51%).
The major components were determined by solvent Hexane: Isobornyl acrylate
(66.89%), 2-Azido-2,3,3-trimethylbutane (6.09%), Ethanolamine (5.41%).
Chemical composition of the essential oil extracted by hydrodistillation (Clevenger
apparatus) from some aerial parts (ripe and unripe fruit) of Pistacia Atlantica
(Anacardiaceae) which are widely spread throughout the countries of the Mediterranea
n
Sea and have been occupying a good part of the mount of Syria was determined by Gas
Chromatography-Mass Spectrometer GC/MS.
The results of analyzing showed that the oil consist of five compounds in ripe and
unripe fruit, and it was found that the component with the highest ratio in both samples is
the same 2-methylbutanal and its ratio 95.713% in the ripe fruit and 94.138% in the unripe
fruit.
The results of this study also show that the essential oil components of the Syrian
Pistacia fruits are completely different from those in different environments due to the
different types of pistacia species which have been studied and the different environmental
conditions in which this plant grows.
Chemical composition of the essential oil of the aerial parts of Artemisia
vulgaris L. (Asteracea), grown in Syria was determined by GC/MS. The oil
obtained by hydrodistillation, was found to contain 55 components, accounting
for 98.82 %.
Neem (Azadirachta indica A. Juss.) is an important tree species that is known to posses anthelmintic, contraceptive, antimicrobial, antidiabetic and sedative properties. Therefore, the present study aimed to identify various compounds present in the
leaf extract of neem and to enlist various biological activities of these compounds through literature survey. Methodology: Extract of neem was obtained by soaking 100 g dry powdered leaves in 1000 mL methanol followed by filtration. This was successively fractioned using n-hexane and chloroform. Results: GC-MS analysis of the chloroform fraction was performed and 7 compounds namely 2-pentanol, acetate (9.72%); decane (8.96%); 11-oxa-dispiro[4.0.4.1]undecan-1-ol (6.56%); nonanoic acid, 9-(3-hexenylidenecyclopropylidene)-, 2-hydroxy-1-(hydroxymethyl)ethyl ester, (Z,Z,Z)- (7.13%); quinoline-4-carboxamide, 2-phenyl-N-n-octyl- (9.79%); nonacosane (44.27%) and tetratriacontane (13.43%) were identified. Conclusion: Literature survey showed that the identified compounds possessed antibacterial, antifungal, anticancer, cytotoxic, anti-inflammatory, antioxidant, and antiviral properties.
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%).
