Aims: This work was carried out to screen for the presence of bacteria in roasted chicken sold in the market, poultries shop and restaurants in Tripoli. Study Design: A total of 25 roasted chicken and 25 raw chicken parts randomly collected from different selling points in Tripoli. Place and Duration of Study: Microbiology laboratory in microbiology and immunology department in the faculty of pharmacy in university of Tripoli, January 2013 to September 2013. Methodology: Bacteriologically examined using the standard microbiological method according to Based on the colonial morphological and biochemical test, the following bacteria species were isolated. Results: Prevalence of Salmonella was higher in raw chicken samples (100%) compared to the roasted one (28%), E. coli was detected in both raw and roasted chicken (32%), whereas Shigella and E. coli O157:H7 were detected only in roasted chicken [(8%) and (24%)] respectively. Conclusion: The study found that the raw chicken samples were more susceptible to bacterial contamination than the roasted chicken samples, therefore special strategies are needed to decrease the prevalence of bacterial pathogens in chicken samples present in Tripoli area. Therefore good handling/hygiene in processing and preheating of roasted chicken before consumption is recommended.

Inflammatory bowel disease (IBD) is a general term describing chronic, idiopathic relapsing, inflammatory conditions of the gastrointestinal tract of unknown etiology. Previous studies have indicated that Malva parviflora leaf extract possesses anti-inflammatory, antioxidant, and antiulcerogenic activity. activity. This work aimed to investigatee the anti-inflammatory effect of the methanolic (MEMP) and aqueous (AEMP) extracts of M. parviflora leaves on acetic acid-induced colitis in rats. arabic 19 English 104

نبات القازول Allium roseum L نبات ينتمي إلى الفصيلة البصلية Alliaceae مستوطنا في شمال أفريقيا. يستعمل هذا النبات خلال فصل الربيع في إعداد بعض الوجبات الشعبية كما يستعمل كبديل عن الثوم Allium sativum.يستهدف هذا البحث دراسة الكيمياء النباتية لنبات القازول لمعرفة المواد الفعالة ولمعرفة القيمة الغذائية ومعرفة تأثيره كمضاد للتأكسد وكمضاد للتخثر.خضعت الأزهار والأبصال الطازجة كلا على حدة إلى التقطير البخاري وذلك لاستخلاص الزيوت الطيارة. كما خضعت الأزهار والأبصال المجففة في الظل للاستخلاص عن طريق عملية النقع في الميثانول في درجة حرارة الغرفة.طبقا لطرق التحاليل الكيميائية المرخصة (AOAC 2002) فإن النتائج أثبتت أن النبات يعتبر مصدرا جيدا للبروتين والدهون والألياف والسكريات حيث كانت (13.436 ±0.23, ,5.503 ±0.26 31.032 ±0.0و29.839±0.19) متتابعة بالنسبة للأزهار؛ (19.361 ±0.26, ,14.813 ±0.09 15.803 ±0.06 و34.714±0.9) متتابعة بالنسبة للأبصال.تم التعرف على التركيب الكيميائي للزيوت الطيارة والمستخلص الميثانولي لكل من الأزهار والأبصال عن طريق استخدام جهاز GC-MS. النتائج بينت أن المركب Triacoctane (40.47%) والمركب Isoelemicin (30.27%) كمكونين أساسيين بالنسبة للزيت الطيار للأزهار؛ والمركب 9,12Tetradecadien1ol,acetate,(Z,E) (88.43%) كمكون أساسي بالنسبة للزيت الطيار المستخلص من للأبصال. كما تم تحليل مستخلصات الميثانول بواسطة GC-MS وتم التعرف على مجموعة من المركبات.هذه الدراسة كشفت أن النبات له تأثير معتدل ضد التأكسد مقارنة بفيتامين ج؛ وأن معدل التأثير المضاد للتأكسد بالنسبة للأزهار أكبر من الأبصال.كما تم دراسة التأثير الخارجي المضاد للتجلط المعروف باسم (وقت البروثرومبين) لمستخلصي الميثانول بأحجام مختلفة (25, 50 و75 ميكروليتر) حيث اختبرت على عينات دم لأشخاص طبيعيين بواسطة قياس وقت البروثرومبين. حيث وجد أنه يزداد الوقت المطلوب للتجلط بازدياد الحجم المضاف من المستخلص وأن مستخلص الأزهار له فعالية أقوى من مستخلص الأبصال .Abstract: This study deals with the chemical characterization of a medicinal and an aromatic plant of the Libyan flora: Allium roseum L, and aimed to identify new bioactive natural compounds in its flowers and bulbs, determine the nutrient and bioactive compounds and screening for their possible antioxidant and anticoagulant properties. The chemical composition of essential oils steam-distillized as well as methanolic extracts of both flowers and bulbs were analyzed by GC/MS. The results showed that the Triacoctane and Isoelemicin were detected as the major components of the flowers essential oil (40.47, 30.27%) repectively. For bulbs essential oil showed that 9,12Tetradecadien1ol, acetate, (Z, E) was detected as the major component (88.43%). The GC-MS analysis of the methanolic extracts of the flowers and bulbs of A. roseum showed the presence of: five compounds in flowers methanolic extract, in terms of percentage amounts 10,13-Octadecadienoic acid, methyl ester (19.92%), 2,2-dimethoxybutane(17.55%), Furan,tetrahydro-2,5-dimethyl (12.02 %) and Hexadecanoic acid, methyl ester (11.68 %); and nineteen compounds in methanolic extract of bulbs, in terms of percentage amounts: Heptadecane (13.96%), Octadecane (10.84%), Tetradeca-(9z,12e)-dienyl acetate (10.47%) and Hexadecane (8.97 %)were predominant in the extract. Association of the official analytical chemists methods (2002) are used for nutritional analysis of flowers and bulbs of A. roseum. Results indicated that this plant is an excellent source ofproteins, fats, fibers and carbohydrates (13.436 ±0.23, 5.503 ±0.26, 31.032 ±0.04 and 29.839±0.19) respectively for flowers and (19.361 ±0.26, 14.813 ±0.09, 15.803 ±0.06 and 34.714±0.9) respectively for bulbs. The study revealed that, A.roseum L had moderate antioxidant, scavenging effect of methanolic extracts of flowers and bulbs when compared with standards (ascorbic acid and quercetin). IC50 (µg/ml) 5 min following the order: quercetin (1.08) < ascorbic acid (2.14) < flower extract (116.17) < bulb extract. Free radical scavenging activity of these samples also increased with an increasing concentration. In vitro anticoagulant effects of methanolic extracts of both flowers and bulbs of A. roseum in different volumes (25, 50 and 75 μL) were examined in the blood samples of normal individuals by measuring prothrombin time (PT). The methanolic extracts of flowers and bulbs of A. roseum were found to inhibit coagulation process in vitro and significantly prolonged prothrombin time in a dose-dependent manner. Methanolic extract of flowers was more potent in prothrombin time prolongation than methanolic extract of bulbs. All results in this project were investigated for the first time on Libyan A. roseum L.
