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.
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.
