Jujube belongs to the Rhamnaceae family and is known as red date or Chinese date. It has widespread uses due its high nutritional values. In this study, jujube fruit seeds grown in Sakarya, Turkey, were extracted their total phenolic flavonoid contents evaluated. The liquid chromatography-high resolution mass spectrometry (LC-HRMS) analyses results showed that 15 different substances identified fruit, while 27 detected seeds. of seed determined 127.91 ± 3.05 mg GAE/g extract (ext) 14.58 5.22...

Red beet (Beta vulgaris L.) is a rich source of phenolic content including colour pigments and have also high antioxidant capacities. The amounts their substances activities change depending on the extraction conditions (pH, time, solvent, etc.). In this work, coloured water extracts were obtained from red at different pH values (pH 4-10) for both an hour 24 hours. evaluated regarding total contents (TPC). results showed that extract in all ranged 0.55±0.02 to 2.30±0.19 mg GAE/g FW. highest...
Red cabbage (Brassica oleracea) is a rich source of phenolic content including colour pigments and have also high antioxidant capacities. The amounts their substances activities change depending on the extraction conditions (pH, time, solvent, etc.). In this work, coloured water extract was obtained from red at different pH values (pH 4-10) for both an hour 24 hours. extracts were evaluated regarding total contents activities. results showed that in all ranged 4.93±0.20 to 7.59±1.22 mg GAE/g...
Tarhana, which is very rich in nutritional value, has been the crown of our tables for centuries and one common values wherever we live. It obtained with black carrot extract to give this special food an even richer form. Black was used increase anthocyanin content tarhana. In study, physical chemical analyzes, total phenolic flavonoid content, antioxidant activities, colour measurement, sensory analysis tarhana prepared were determined. At same time, amount monomeric All these compared...
In this study, a series of thiophenyl-chalcones derivatives was synthesized and their DPPH ABTS activities were evaluated. All exhibited high antioxidant activity. Among them, 4e ((E)-5-(3-(4-(chlorosulfonyl)-3-hydroxyphenyl)-3-oxoprop-1-en-1-yl)thiophene-2-sulfonyl chloride) have higher activity (IC50 = 13.12 μM) than quercetin 15.49 μM), well-known as agent used standard. The structure-activity relationship results revealed that most sulfonyl chloride (4a-e) the sulphonamide (5a-c) also 4d...
Kırmızı pancar (Beta vulgaris L.), renk pigmentleri içeren zengin bir fenolik madde kaynağına veayrıca yüksek antioksidan kapasiteye sahiptir. Fenolik miktarları ve aktiviteleriekstraksiyon koşullarına (pH, süre vb.) bağlı olarak değişmektedir. Bu çalışmada kırmızı pancardan farklıpH değerlerinde (pH 4-10) hem 1 saatlik de 24 ekstraktları elde edilmiştir. Elde edilen buekstraktlar toplam içerikleri aktiviteleri açısından değerlendirildi. Sonuçlar, toplamfenolik içeriğin 0,55±0,02 ile...
Siyah havuç (Daucus carota L. ssp.sativus var. atrorubens Alef.) rengini de veren yüksek düzeyde stabil antosiyanine ve fenolik asitlere, bu nedenle antioksidan, antitümör, antimikrobiyal antiinflamatuarözelliklere sahiptir. posası ise daha polifenol biyoyararlanımı antosiyanin içerir, endüstriyel atık olması açısından da gıda endüstrisinde doğal renklendirici olarak çeşitli gıdalarda kullanılmasının yanı sıra madde değerlendirilebilir. Bu çalışmada kuru siyah posasının metanol ile ekstraktı...
Elma, (Malus Domestica) çok eskilerden beri bilinen, taze olarak ya da meyve suyu, şarap, reçel gibi ürünlerin üretiminde değerlendirilen Dünya’da en tüketilen dördüncü meyvedir. Elma posası ise işleme prosedürleri sırasında büyük miktarlarda ortaya çıkan, çevre kirliliğine ve ekonomik kayıplara neden olan genellikle atık ürün işlenen bir üründür. 60'ın üzerinde farklı fenolik bileşik içermesiyle kanser, kalp hastalıkları, diyabet, kalp-damar hastalıkları birçok önemli hastalığa olumlu etki...
Meyveler ve sebzeler zedelenme, kesilme soyulma gibi durumlara maruz kaldığında içeriklerinde bulunan fenolik bileşiklerin oksidasyonu sonucu melanin adındaki kahverengi bir kimyasal oluşumu ile beraber hızla kararırlar. Bazı maddeler enzimatik esmerleşme reaksiyon ortamında bulunan, renk değişimine sebep olan o-kinonları geriye, yani formlara indirgeme özelliğine sahiptir. Bu sayede reaksiyonu durmakta bozulmamaktadır. çalışmada mürdüm eriği (Prunus domestica subsp. Insititia) kabuğundan...
Primula longipes boiss is a member of the Primulaceae family and found growing on wet grassy slopes or benches, moist crevices at altitudes 1625-3400, in Black Sea region across Rize, Trabzon, Artvin, Gümüshane, Giresun. Studies suggest that it has been used traditional remedies. The known to possess antioxidant properties contains saponins, alkaloids, tannins, terpenes, several flavonoids. In this study, an extract (Primrose) was obtained using soxhlet device then make cold cream. capacity...
