Grapefruit (Citrus Paradisi) is one of many citrus species that are widely cultivated in the west Mediterranean coast of Syria, the fruit is rich in flavonoid (a natural medical compounds), naringin considered the major flavonoid in Grapefruit. Previous studies have documented a wide range of biological effects and therapeutic properties that belong to naringin; therefore, it became a raw material in pharmaceutical industries. It was the aim of this study is to have naringin extracted from grapefruit by an economic method, and assign its levels, in preparation for industrial investment. Two types (red blush) and (march) where collected from three districts in Syrian coast, they were collected at the beginning of harvest season and at the end of it, fruits grown in sun light and those grown in shade were collected tow, so that healthy fruit and partly infected. A water alkaline method was applied to extract naringin, then a quantitive and qualitative determination was made to the resulting compound. Results revealed that naringin content in March grapefruit at the beginning of the harvest season was 45.53 g/kg and 44.8 g/kg in Red Blush grapefruit so on at the end of the harvest season it was 10.29 g/kg in March and 9.32 g/kg in Red Rlush. We have concluded that that Syrian Grapefruit have sufficient naringin cotent for economical investment, and that water alkaline method is a suitable economic method to extract naringin from grapefruit white peels.

Research summary
تتناول هذه الدراسة تحديد مستويات النارنجين في ثمار الغريفون المزروعة محلياً في الساحل السوري. النارنجين هو مركب فلافونوئيدي رئيسي في الغريفون وله فوائد صحية متعددة، مما يجعله مادة مهمة في الصناعات الصيدلانية. جمعت العينات من ثلاثة مناطق مختلفة في الساحل السوري في بداية ونهاية موسم الحصاد. استخدمت طريقة الماء المقلون لاستخلاص النارنجين من القشور البيضاء للغريفون. أظهرت النتائج أن كمية النارنجين في الغريفون الأبيض كانت أعلى قليلاً من الغريفون الأحمر، وكانت الكميات في بداية الموسم أعلى من نهايته. تبين أن الغريفون السوري يحتوي على كميات كافية من النارنجين للاستثمار الاقتصادي، وأن طريقة الماء المقلون هي طريقة اقتصادية وفعالة لاستخلاص النارنجين. توصي الدراسة بجني الثمار في بداية الموسم للحصول على أكبر كمية من النارنجين، وتحسين درجة حموضة التربة لتحسين الإنتاج.
Critical review
دراسة نقدية: تعتبر هذه الدراسة مهمة لأنها تسلط الضوء على إمكانيات استثمارية جديدة في مجال الزراعة والصناعة الصيدلانية في سوريا. ومع ذلك، هناك بعض النقاط التي يمكن تحسينها. أولاً، كان من الممكن توسيع نطاق الدراسة لتشمل مناطق أخرى من سوريا للحصول على نتائج أكثر شمولية. ثانياً، لم تتناول الدراسة بشكل كافٍ تأثير العوامل البيئية الأخرى مثل التربة والمناخ على مستويات النارنجين. ثالثاً، كان من الممكن استخدام تقنيات تحليلية أكثر تقدماً للحصول على نتائج أكثر دقة. وأخيراً، كان من الأفضل تضمين دراسة اقتصادية مفصلة لتحديد الجدوى المالية لاستثمار النارنجين.

Functional foods are similar to conventional food and demonstrate beneficial effects beyond their nutritional value. These effects are attributed to the presence of functional ingredients. Functional ingredients can either be found naturally in a c ertain food or added to it. There’s a number of functional food products available in the market. For example, natural functional juices containing polyphenols. The aim of this study is to determine total phenolic content and antioxidant activity in some local functional juices. Total phenolic content was determined according to Folin- Ciocalteu method. The highest in content was mulberry juice, while the lowest was red grape juice. The best conditions for eliminating ascorbic acid were also determined which were heating for 30 min at 75°C. Antioxidant activity was subsequently determined using potassium ferricyanide. The highest in phenolic content among the studied juices were the highest in antioxidant activity. Thus a strong correlation was found between total phenolic content and antioxidant activity.
The concentrations of Copper (Cu) and Zinc (Zn) in samples of some spices available at some local markets in Syria were determined, after nitric digestion, using Atomic Absorption Spectrometry. The study showed differences in metal concentrations according to the edible part. Studied heavy metals were present in all samples at different levels. The concentration of Copper (Cu) and Zinc varied from trace to higher concentration. The maximum level of Copper (Cu) in the spices samples was 0.668 mg/kg. The maximum level of Zinc (Zn) in the spices samples was 2.523mg/kg. The analytical results obtained for the heavy metals indicate that the Copper and Zinc were present in all samples at concentration well below the acceptable daily intake recommended by the World Health Organization.
The concentrations of copper (Cu) and zinc (Zn) in samples of some cereals available at local markets in Syria weredetermined, after nitric digestion, using Atomic Absorption Spectrometry. The study showed that the heavy metals were present in all samples at different levels. The concentration of heavy metals varied from trace to higher concentration. The maximum level of copper (Cu) in the cereal samples was 0.426 mg kg-1 on dry weight basis, where the maximum level of zinc (Zn) in the cereal samples was 2.325mg mg kg- 1 on dry weight basis. The analytical results obtained for the heavy metals indicate that the copper and zinc were present in all samples at concentration well below the acceptable concentration recommended by the World Health Organization.
The Arak and Wine are common alcoholic spirits in Syria. However, those spirits are often produced outside the controls of the manufacturing cycle in terms of fermentation and distillation, thus exposing the consumers to risk of methanol poisoning, w hich confirms the need to submit their production to the control as extremely essential. The aim of this study to determination of methanol in some alcoholic beverage prepared by traditional local methods in order to verify conformity of local Alcohol Syrian standard specification. The samples were tested by using colorimetric method as official methods depending on the measurement using spectrophotometer at (575 nm).In comperation with the standard Syrian specifications number /2478/ year (2003), there were fifty test samples (Arak and Wine) collected from locally available. The study showed the amount of variation in the concentration of methanol depending on the difference in the method of preparation fermenting grapes. furthermore the importance of applying the control system to provide the quality of those popular spirits.
The aim of the present study was to determine the levels of lead and cadmium in the meat, liver and kidney of sheep exposed in the local markets of the city of Latakia, and to compare the results with those reported by other countries and with the maximum acceptable levels for human consumption, Lead and cadmium were determined by atomic absorption spectrometry (AAS). The mean concentrations of lead in meat, liver and kidney were 0.043, 0.284 and 0.118 mg/kg fresh weights, respectively, while mean concentrations of cadmium were 0.017, 0.173 and 0.252 mg/kg fresh weights, respectively. Statistical analysis showed a significant difference in lead and cadmium concentrations between liver and kidney and in meat.
