In October 2014, the collected air-green samples of Basil herb were gathered from the region of MashtaAlhulu in the ,Then the volatile oil from fresh samples was extracted with N-Hexane and other samples with steam distilled water, and we have found the percentage of the volatile oil in the first sample (N-Hexane) is 2,7% , and 2,5% in the second sample (steam distilled water). Suitable conditions were chosen to separate the components of the volatile oil by GC-MS and we noticed : - the first sample (extracted with N-hexane) contain 18 compounds, and they are: Six Terpenes compounds and they form 21.22%,Hydrocarbon compounds form 21.8% from the total weight and they are 7 compounds, and one compound from Ketone class dicycle and its percentage is 2.32%,and two Ester compound and they form 18.96%, One phenolic compound and forms 21.60%, one Ether compound and forms 14.08%. -the volatile oil from the second sample (extracted with steam distilled water) contains 11 compounds, and they are: 6 compounds belong to Hydrocarbon class and they are the main components in the volatile oil with a 91.24% of the oil total weight, One compoundfrom Ether class forms 1.62%, one phenolic compound which forms 3.93%, and three Terpenes compounds and they form 3.17%.

Research summary
تتناول هذه الدراسة التي أجراها الدكتور عماد الحداد استخلاص الزيت العطري من أوراق نبات الريحان (الحبق) وتحليل مكوناته الكيميائية باستخدام جهاز GC/MS، بالإضافة إلى تقييم فعاليته المضادة للجراثيم. تم جمع العينات من منطقة مشتى الحلو في سوريا في أكتوبر 2014، واستخدمت طريقتان للاستخلاص: النقع بالهكسان النظامي والجرف ببخار الماء. أظهرت النتائج أن نسبة الزيت العطري المستخلص بالنقع بالهكسان كانت 2.7% بينما كانت 2.5% باستخدام الجرف ببخار الماء. تم تحديد 18 مركباً في الزيت المستخلص بالنقع، بينما تم تحديد 11 مركباً في الزيت المستخلص بالجرف ببخار الماء. أبرز المركبات في العينة الأولى كانت التربينات والهيدروكربونات والفينولات، بينما كانت الألكانات هي المكون الرئيسي في العينة الثانية. أظهرت الدراسة أن الزيت العطري له تأثير مثبط لنمو الجراثيم العنقودية المذهبة والعصيات القولونية، مع فعالية أكبر ضد الجراثيم العنقودية المذهبة.
Critical review
دراسة نقدية: تعتبر هذه الدراسة خطوة مهمة في فهم مكونات الزيت العطري لنبات الريحان وفعاليته المضادة للجراثيم. ومع ذلك، كان من الممكن أن تكون الدراسة أكثر شمولاً إذا تم تضمين المزيد من العينات من مناطق مختلفة لتحليل تأثير العوامل البيئية على مكونات الزيت. كما أن الدراسة ركزت بشكل كبير على التحليل الكيميائي ولم تتناول بشكل كافٍ التطبيقات العملية للزيت العطري في المجالات الطبية والصناعية. بالإضافة إلى ذلك، كان من الممكن أن تكون الدراسة أكثر قوة إذا تم تضمين تجارب إضافية لتقييم تأثير الزيت العطري على أنواع أخرى من الجراثيم والفطريات.

The aim of this study is to determine the essential oil of Ocimum and to find out the chemical constituents of essential oils of Yemeni Ocimum basilicum Lamiaceae.
This research was carried out to determine the quantity of essential oil extracted from myrtle Myrtus communis L leaves, by hydro distillation, and to identify the major and minor components, besides to determine its quantities in the essential oil by Gas Chromatography-Mass Spectrometry GC-MS. The samples were collected on November 2013 from eight different climatic locations (Aleppo, Zarzour, Alzenea, Katra AL-Rayhan, Al- Rayhana, Kasab, Mashta al-Holou and Mosiaf). The quantity and composition of the essential oil were estimated on the basis of the leaves dry weight. Oil quantity varied between the studied genotypes from different locations, which range from 0.46 to 0.55 ml, with non-significant differences. Eighteen compounds were identified in myrtle essential oil, and there were significant differences in 13 compounds. 1,8-Cineole performed the highest rate (18.85%) compared with other components, followed by α-Pinene (16.93%). While the lowest percentage was (0.31%) of Myrcene. The
The antibacterial activity of Golden henbane (Hyoscyamus aureus) on several species of bacteria: Pseudomonas aeruginosa, Staphylococcus aureus and Escherichia coli was determined. Samples of H. aureus plants were collected from six locations in southern Syria. The extract of roots and leaves of H. aureus were prepared at concentrations.
Six Syrian landraces of Rosa damascena planted at the faculty of agriculture of Damascus University have been evaluated in this study. A big variation of yield was noticed among the landraces. The landrace called (Mesraba) was superior to others c oncerning yield which was (112.2 g/plant). On the other hand, (Erna) had got the highest content of oil (0.071%). Analysis of oil implemented in Suleyman Demirel University in Turkey (Isparta) identified the main components of oil such as: Geraniol (28-31%), Citronellol (26-30%), Nerol (12-14%), Germacrene-D (6-8%), Nonadecane (4-6%) and Linalool (1- 3%). Besides, many trace compounds were detected such as: Eicosane, Eugenol, Citral, Hexadecane and Rose oxide. The essential oil of (Almarah) had got the highest quality.
This study was conducted at the laboratory of Food Science Department, Agriculture College, Damascus University to isolate and characterize of Lactobacilli bacteria from some Syrian foods and detection the effectiveness of anti-pathogenic bacteria l growth. Lactic acid bacteria from different dairy products, pickles and dried plant samples were isolated and identified according to common characteristics. Results showed that twenty-three isolates were rods while only 2 of the them were coccid. These isolates were tested for their antimicrobial effect against pathogenic bacteria for both gram positive bacteria (Staphylococcus aureus) and gram negative bacteria (Klebsiella pneumonia and Escherichia coli). Fifteen isolates demonstrated antimicrobial effect against the three tested bacteria, of which CP50 and CP46 isolates showed the best antimicrobial effect. Results of the standard physiological and biochemical tests identified fourteen isolates as Lactobacillus plantarum and one isolate as Lactobacillus fermentum.
