Öğe Bioactive content of Rosa canina biotypes from Turkey(Scibulcom Ltd., 2017) Beyhan O.; Koc A.; Ercisli S.; Jurikova T.; Cakir O.Rose hips have been used as medicinal and aromatic plants for a long time throughout Turkey. The plant has been the focus of many recent studies due to its potential effects on treatment and prevention of several diseases. However, there are few in vitro studies concerning its composition and antioxidant capacity. The aim of the present study was to determine bioactive content including ascorbic acid, total phenolics, total flavonoids, total carotenoids and antioxidant activity of Rosa canina biotypes growing wild in Sivas province located eastern Anatolia. The results revealed that fruits of Rosa canina biotypes rich in terms of Vitamin C which ranged from 360 to 482 mg/100 g fresh weight base. The total phenolic content varied from 340 to 464 mg/100 g fresh weight. The biotype S-07 had the highest total flavonoids content (241 mg quercetin equivalent/100 g fresh weight) and the lowest value attributed to biotype S-01 as 151 mg/quercetin equivalent/100 g fresh weight. The antioxidant activity of the biotypes was between 14.2-30.7 ?g Trolox/ml sample. The results revealed that there was enough diversity among Rosa canina biotypes for bioactive content and promising biotypes with high bioactive content are ready material for future breeding activities.Öğe Bioactive content of rose hips of different wildly grown rosa dumalis genotypes(Academic Press, 2016) Alp S.; Ercisli S.; Jurikova T.; Cakir O.; Gozlekci S.A rose hip is the fruit of a rose plant and mostly belongs to Rosa canina and Rosa dumalis. These species are genuine found as wild in natural conditions, while in some countries are cultivated for their hips that are picked and used in a wide variety of preparations. Because they contain a variety of antioxidants, carotenoids, flavonoids, polyphenols, leucoanthocyanins and catechins, rose hips are considered to be a good cancer preventative. The Rosa genus has been the focus of many recent studies due to its potential benefic effects on treatment and prevention of several diseases. However, there are few in vitro studies concerning its composition and antioxidant capacity. The aim of the present study was to determine bioactive content, including ascorbic acid, total phenolics, total flavonoids, total carotenoids and antioxidant activity of Rosa dumalis genotypes growing wild in Erzurum province located eastern Anatolia. The results revealed that fruits of Rosa dumalis different genotypes were rich rich in terms of vitamin C, which ranged from 402 to 511 mg/100 g fresh weight base. The total phenolic content varied from 297 to 403 mg/100 g fresh weight. The genotype 'E-09' had the highest total flavonoids content (229 mg quercetin equivalent/100 g fresh weight) and the lowest value was attributed to genotype 'E-04' with 143 mg/ quercetin equivalent/100 g fresh weight. The antioxidant activity of the genotypes was between 12.9-28.6 ?g Trolox/ml samples. The results revealed that there was enough diversity among Rosa dumalis genotypes for bioactive content and promising genotypes, with high bioactive content, were determined, which can become study material for future breeding activities.Öğe Biodiversity and Landscape Use of Sea Buckthorn (Hippophae rhamnoides L.) in the Coruh Valley of Turkey(Springer Verlag, 2015) Sezen I.; Ercisli S.; Cakir O.; Koc A.; Temim E.; Hadziabulic A.The Sea buckthorn, one of the most important wild edible fruits widely grown in Northeastern part of Turkey, is characterized by resistance to hard environmental conditions and looks spectacular, especially in autumn and winter when it is decorated with orange berries. Climatic conditions in Northern Anatolia are suitable for the growing of the Sea buckthorn, which can be encountered in various dry areas as well as by riversides. Local people traditionally processed or preserved sea buckthorn fruits (berries). The decorative sea buckthorn shrubs/trees and berries are an important element of natural landscape in Northeastern Anatolia. The aim of the study was to define the biodiversity among trees/shrubs, berries and leaves of the Sea buckthorn accessions based on morphological and biochemical data. Results showed a high diversity among accessions in terms of plant, leaf and berry characteristics. Berry diameter, length and 100 berry weight ranged from 5.48 to 7.18 mm; 6.64 to 9.14 mm and 15 to 26 g, respectively. A wide variability of berry skin colour was observed to be yellow, light yellow, dark yellow, yellow orange, orange and dark orange. The anthocyanin content varied from 7 to 38 mg/l berry juice. © 2014, Springer-Verlag Berlin Heidelberg.Öğe Morphological, Biochemical and Antioxidant Properties of Local Loquat (Eriobotrya Japonica (Thunb.) Lindl.) Germplasm from Turke(Springer Verlag, 2017) Akbulut M.; Gozlekci S.; Ercisli S.; Cakir O.Loquat (Eriobotrya japonica L.) grown well for commercial purposes in subtropical regions nearly 30 countries and originated from China. The most important loquat producers in the world are China, Spain, Turkey, Pakistan, India, Italy and Brazil. In this study, ten pre-selected promising loquat genotypes sampled from eastern Black region and analyzed for their important morphological, biochemical and antioxidant characteristics. The standard cultivar ‘Sayda’ is also included in the study. The results indicated differences for all of the morphological, biochemical and antioxidant characteristics among tested genotypes. Fruit mass and fruit flesh percentage of the genotypes ranged from 35.40 g (LOQ-8) to 46.90 g (LOQ-5) and from 79.40 (%) to 86.32 (%) indicating some local genotypes had higher fruit mass and fruit flesh percentage than standard cultivar ‘Sayda’. Total phenolic content was the highest as 263 ?g GAE/g in LOQ-7 genotype while the lowest in LOQ-8 genotype (185 ?g GAE/g). LOQ-7 genotype had the highest total antioxidant capacity. Local genotypes in general have higher total phenolic, total carotenoid, vitamin C and antioxidant activity than cv. ‘Sayda’. © 2016, Springer-Verlag Berlin Heidelberg.Öğe Organic acids, sugars and mineral content of cherry laurel (laurocerasus officinalis roem) accessions in Turkey(Academic Publishing House, 2016) Esringu A.; Akši? M.F.; Ercisli S.; Okatan V.; Gozlekci A.; Cakir O.In this study we report on the content of organic acids, sugars and miner-als in the pulps of the twelve cherry laurel accessions most commonly consumedin eastern Black Sea Region. Malic acid was the dominant organic acid rangedfrom 43.27 (CL6) to 54.23 (CL3) mg/100 g fresh weight basis. The dominantsugars were glucose and fructose in the pulps that ranged from 4.83 (CL1) to5.74 (CL5) mg/100 g and 4.66 (CL3) to 5.53 (CL7) mg/100 g, respectively. Thepulp of cherry laurel was shown to be rich in potassium (187-241 mg), phos-phorus (26-45 mg), calcium (15-22 mg), magnesium (15-24 mg) and sodium(3.9-6.1 mg) in 100 g fruit pulp.

Fruits from Turkey(Springer Verlag, 2014) Yildiz H.; Ercisli S.; Sengul M.; Topdas E.F.; Beyhan O.; Cakir O.; Narmanlioglu H.K.; Orhan E.Increasing consumer demands for indigenous, non-sprayed with pesticides and less-known or “forgotten” fruits necessitate knowledge on their breeding, cultivation, biochemical content, harvesting and marketing. Anatolia is rich for wild edible fruit species and barberry is abundant throughout Anatolia. The aim of this study was to determine some important physicochemical characteristics, bioactive content and antioxidant capacity of fruits from nineteen promising barberry (Berberis vulgaris L.) genotypes grown in the Coruh valley, Northeastern Anatolia. The results indicated genotype-specific differences for most of the physicochemical characteristics, antioxidant capacity and the content of some bioactive compounds. Fruit mass ranged from 0.073 (‘Coruh-7’) to 0.267 g (‘Coruh-11’). Total phenolic content ranged from 2532 (‘Coruh-’) to 3719 mg GAE per liter fruit juice (‘Coruh-11’). The genotype ‘Coruh-12’ had the highest total monomeric anthocyanin content (1004 mg per liter fruit juice) as cyanidin-3-glucoside. The highest total antioxidant capacity was observed in fruits of ‘Coruh-8’ and ‘Coruh-9’ genotypes with all three antioxidant-determining methods. We conclude that the barberry fruits represent a good source of bioactive phytochemicals because of their high phenolic and anthocyanin contents. © 2014, Springer-Verlag Berlin Heidelberg.Öğe Some physicochemical properties of wild and cultivated pomegranates (Punica granatum L.)(Scibulcom Ltd., 2017) Gozlekci S.; Ercisli S.; Choudhary R.; Cakir O.; Sagbas H.I.The fruits of seven wild grown pomegranate genotypes and well-known cultivar Hicaznar were analysed for several physical (fruit mass, shape index, calyx length, peel yield, peel thickness, aril yield and juice yield) and chemical (soluble solid content, titratable acidity, pH, soluble solid content/acidity, total phenolic content, antioxidant activity and total anthocyanin) properties. There were statistical differences within wild genotypes and also between wild genotypes and cv. Hicaznar in terms of most of the parameters. The average fruit mass ranged from 127-192 g among wild genotypes and cv. Hicaznar had 394 g fruit mass. The wild genotypes, in general, had lower aril and juice yields than cv. Hicaznar. However they have higher total phenolic content and antioxidant activity than cv. Hicaznar.
