نظراً لأهمية نبات القبّار الشوكي من الناحية الاقتصادية و الطبية, و لانتشاره الواسع في البيئة السورية, فقد شكل ذلك أساساً للقيام بدراسة أولية للمكونات الأساسية للزيت العطري المستخلص من هذا النبات. تم استخلاص الزيت العطري و تنقيته, و من ثم درست مكوناته الأساسية باستخدام جهاز التفريق اللوني الغازي الكتلوي (الكروماتوغرافيا الغازية الكتلوية GC-Mass spectrometry). و استخلص الزيت العطري بطريقة الجرف بالبخار (التقطير البخاري) باستخدام جهاز كليفنجر و بطريقة النقع باستخدام الهكسان كمذيب. و تم التعرف على 37 مكوناً من مكوناته التي شكلت حوالي 98.9% من المجموع الكلي للزيت العطري. و كانت المكونات الرئيسية للزيت العطري في حالة الجرف بالبخار هي: Palmitic acid (21.12%), Hexatriacontane (15.87%), n-Heneicosane (10.96%), Pentatriacontane (9.92%), Hexahydrofarnesyl acetone (8.51%). أما المكونات الرئيسية للزيت العطري المستخلص بالمذيب (الهكسان) كانت كالتالي: Isobornyl acrylate (66.89%), 2-Azido-2,3,3-trimethylbutane (6.09%), Ethanolamine (5.41%)
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 Capparisspinosa 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%).

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%).
Due to the economical and medical importance of the Melilotus plant and the wide
distribution of this plant in the Syria environment, it was of necessity to study the the
composition of organic matter extracted from the leaves of this plant.
The M
elilotus Officinal organic matter was extracted and purified their where were studied
by GC-Maas spectrometry.
The organic matter was obtained by Soxhlet extractor and by solvent n-Hexane.
Components have been found which was about (99.91%) from the total of Essential Oil.
The major components were extracted by Soxhlet extractor and the following components
were determined : n-Docosane(39.82%) , Hydrocoumarin(15.39%) ,
Methyl 3-(2-hydroxyphenyl)propionate(14.29%).
The major components were determined by solvent n-Hexane:
1,2-Benzenedicarboxylic acid(17.77%) , 9,12,15-octadecatrienoic acid(12.85%)
The effects of the extracted aromatic oil from the leaves of Melilotus plant on some of
Pathogenic Microorganisms were studied.
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.
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.
