The main properties(yield of juice, total soluble solid, pH, total acidity, total sugars), some antioxisant compounds as (vitamin C, carotenoids, total phenol, anthocyanins), and antioxidant activity measured by DPPH method for some main Syrian orange cultivars (navel, valancia, blood orange, and shamouti) were investigated. The results showed that valancia was the highest in juice yield (55.16%), while navel had the highest content of carotenoids(8.68mg/100g) and the lowest one of vitamin C(31.53mg/100g). Whereas, blood orange was superior in its content of total phenolic (295.73 mg gallic acid100/g) and antioxidant activity, (74.833%) among the studied cultivars.

Research summary
تتناول هذه الدراسة الخصائص الفيزيائية والكيميائية لبعض أصناف البرتقال المزروعة في سوريا، بما في ذلك مردود العصير، المواد الصلبة الذائبة، الحموضة الكلية، السكريات الكلية، وبعض المركبات المضادة للأكسدة مثل فيتامين C، الكاروتينات، الفينولات الكلية، والأنثوسيانينات. تم قياس النشاط المضاد للأكسدة باستخدام طريقة DPPH. أظهرت النتائج أن صنف فالنسيا كان الأعلى في مردود العصير بنسبة 55.16%، بينما كان صنف أبوسرة الأعلى في محتواه من الكاروتينات (8.68 مغ/100غ) والأقل في محتواه من فيتامين C (31.53 مغ/100غ). تفوق صنف الماوردي في محتواه من الفينولات الكلية (295.73 مغ حمض الغاليك/100غ) والنشاط المضاد للأكسدة بنسبة 74.83%. تشير النتائج إلى أن الاختلافات بين الأصناف تعود إلى التباين في الظروف البيئية والجغرافية والوراثية.
Critical review
دراسة نقدية: تعد هذه الدراسة مفيدة في تقديم معلومات شاملة حول الخصائص الكيميائية والفيزيائية لأصناف البرتقال المزروعة في سوريا. ومع ذلك، يمكن تحسين الدراسة من خلال تضمين مزيد من التفاصيل حول الظروف البيئية والجغرافية التي قد تؤثر على النتائج. كما يمكن توسيع نطاق الدراسة لتشمل أصناف أخرى من البرتقال لمزيد من الشمولية. بالإضافة إلى ذلك، قد يكون من المفيد استخدام تقنيات تحليلية متقدمة لتحليل المركبات الفعالة بيولوجياً بشكل أكثر دقة.

In this research, the antioxidant capacity(DPPH method), and total phenolic content (assayed by Folin-Ciocalteu method), ,flavonoids, anthocyanins (pH differential method) and ascorbic acids(2,6-dichlorophenol indophenol) in three fruit tissues ( peel, pulp and whole fruit), of four apple cultivars commonly in Syria(Red Delicious, Rome Beauty, Starking Delicious, Golden Delicious), were studied.
Classified locality Yeasts have been culturing in plantology department at the Faculty of Science-University of Damascus, from genera of Pichia, Candida, Geotrichum, Rhodotorula, Phaffia on solid Czhapek agar medium, and after incubated in appropr iate conditions their colonies showed evidence of different colors to produce a variety of pigments. Then it cultured in liquid Czhapek medium to increase biomass and the genera producing endocellular pigment separated from the medium by filtration with added ethanol on them and blasting cells by ultrasonic waves to get a pigment, while the genera producing exocellular pigment is separated about the liquid medium also by filtration but the solvent was added to the medium containing the pigment.
This research studied the impact of planting location and cooking time periods of (5, 10, 15, 20 and 40 minutes) on the antioxidant effect, and on the total Phenols and Flavonoids contents using five different samples of Syrian onions. The results showed that the total Phenols, total Flavonoids and antioxidant activity contents were between (279-583)mg/100g dry wt, (80-180)mg/100g dry wt, and (60-75%) respectively. In addition, boiling for different periods resulted in increased total Phenols from (383 to789)mg/100g dry wt and in total Flavonoids from (124 to 205)mg/100g dry wt as well as an increase of (77% to 88%) of antioxidant activity as measured using the DPPH method.
The antioxidant activity of pomegranate juices extracted by two methods was determined using three methods: β- carotene, Linoleic acid emulsion, and DiPhenel Picryl Hydrazyl (DPPH). The juice was extracted by separation arils from fruits and squee zed using Cyclone machine (T-1), while the second extraction method included squeezing the whole halve fruit with previous machine, (T-2). The potential compounds were determined using ethanol in a comparison with Butylated hydroxyl Anisole (BHA) as reference antioxidant. There were significant differences (P<0.05) in the antioxidant activity between the treatments in all measuring methods. The means of antioxidant activity amounted to 82.66% in T-1, 86.82% in T-2 and 86.98% in BHA. There was significant relationship between total phenols and antioxidant activity in all treatments.
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.
