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 Melilotus 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.

Research summary
تعتبر دراسة المركبات الكيميائية العضوية لمستخلص أوراق نبات الحندقوق (Melilotus Officinalis) باستخدام تقنية GC-MS وتأثيره على بعض الأحياء الدقيقة المرضية من الدراسات الهامة نظراً للأهمية الاقتصادية والطبية لهذا النبات وانتشاره الواسع في البيئة السورية. تم استخلاص الزيت العطري من أوراق النبات باستخدام طريقتين: جهاز سوكسيليه وطريقة النقع بالهكسان. تم تحديد 34 مكونًا رئيسيًا للزيت العطري باستخدام تقنية الكروماتوغرافيا الغازية مع مطيافية الكتلة (GC-MS)، حيث كانت المكونات الرئيسية هي n-Docosane (39.82%)، Hydrocoumarin (15.39%)، وMethyl 3-(2-hydroxyphenyl)propionate (14.29%). كما تم دراسة تأثير الزيت العطري على بعض الأحياء الدقيقة المرضية من خلال تحديد التركيز المثبط الأصغري (MIC). أظهرت النتائج أن الزيت العطري المستخلص له تأثير مثبط على نمو بعض الجراثيم والفطريات، مما يبرز أهمية هذا النبات في التطبيقات الطبية والعلاجية.
Critical review
دراسة نقدية: تعتبر هذه الدراسة خطوة مهمة نحو فهم المركبات الكيميائية لنبات الحندقوق وتأثيرها البيولوجي، إلا أن هناك بعض النقاط التي يمكن تحسينها. أولاً، الدراسة تركز بشكل كبير على التحليل الكيميائي دون تقديم تفاصيل كافية عن الآليات البيولوجية التي تجعل هذه المركبات فعالة ضد الأحياء الدقيقة. ثانياً، الدراسة لم تتناول تأثيرات الجرعات المختلفة من المستخلصات على الأحياء الدقيقة بشكل مفصل، مما يحد من فهمنا لكيفية استخدام هذه المركبات في التطبيقات الطبية. ثالثاً، كان من الأفضل توسيع نطاق الأحياء الدقيقة المختبرة لتشمل أنواعاً أكثر تنوعاً، مما يعزز من شمولية النتائج. وأخيراً، الدراسة لم تتطرق إلى تأثيرات المستخلصات على الخلايا البشرية أو الحيوانات، مما يجعل من الصعب تقييم سلامة استخدام هذه المستخلصات في التطبيقات الطبية.

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%).
Bioeffect of some Syrian Myrtus communis L. leaves extracts in growth of some pathogenic microorganisms, which were isolated from Al-Assad hospital laboratory in Lattakia, was tested by disc diffusion method. Results showed that cold and hot water ex tracts have antibacterial activity against all Gram positive and negative bacteria, and pathogenic Candida albicans except Klebsiella pneumoniae. All organic extracts have antibacterial activity against Proteus vulgaris, Entrococcus faecium, Staphylococcus aureus and Staphylococcus albus. Pseudomonas aeruginosa and Pseudomonas fluorescens were affected by most of the organic extracts, and the most bioactivity was by methanol extract, and all inhibition zones of extracts were bigger than inhibition zones by control antibiotics. Serratia marcescens and Acinetobacter calcoaceticus were affected by methanol (with highest inhibition zone 37.33 and 27.33 mm respectively), ethanol, acetone and ethyl acetate extracts, but resistant to the others. Klebsiella pneumoniae affected by ethanol extract only with inhibition zone 20.33 mm. Results of bioactivity according to a various solvents used in this study demonstrate that Syrian Myrtus communis L. leaves extracts have antimicrobial activity, so expected to be potential sources of natural antibacterial and antifungal products against some pathogenic bacteria and fungi in the future.
Phenols were studied in the leaves of Syrian olive varieties collected from (Harasta and Ghouta, Damascus Countryside and Qalamun). Phenolic compounds were extracted from the olive leaf varieties after disposal of plant pigments and fatty compounds, and total phenols separated with solvent (methanol - water).
In field's experiment had been done in the Tartus governorate during the growing season (2013-2012) Different rates of organic fertilizers were used, the experimental transactions were (10) treatments, control (without fertilization) sheep wastes(10- 20-30)tn/h, cow wastes(10-20-30)tn/h, poultry wastes(10-20-30)tn/h. This study aimed to know the effect of adding these fertilizers on biological properties of the soil (the number of physiological groups of microorganisms, and soil respiration). The Results showed increasing in the number of Hertotrophic bacteria , Actenomycetes in the soils which were fertilized in poultry wastes(20),(30)tn/h, and increasing in the number of(bacteria, using mineral from nitrogen, and decomposed of celluose micro organisms) in the soils which were fertilized in poultry wastes(30)tn/h and cow wastes(30)tn/h. As for fertilization, The Results showed decreasing pH in the soils which were fertilized cow wastes(30)tn/h, while soil contents of available P and K and organic mater increased in soil which were treated fertilized in poultry wastes(20),(30)tn/ h, and cow wastes(30)tn/h.
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%).
