Öğe Color and Antioxidant Characteristics of Some Fresh Fig (Ficus carica L.) Genotypes from Northeastern Turkey(Springer, 2012) Ercisli, Sezai; Tosun, Murat; Karlidag, Huseyin; Dzubur, Ahmed; Hadziabulic, Semina; Aliman, YasminaFruit skin color, total phenolics, total anthocyanins, soluble solids content, titratable acidity and total antioxidant capacity in fresh fruits of a number of local and well-known fig (Ficus carica L.) genotypes and cultivars grown in northeastern Turkey were determined. TEAC (Trolox equivalent antioxidant capacity) and FRAP (ferric reducing antioxidant power) assays were used to determine total antioxidant capacity. Fruit skin color of genotypes were found to be very diverse, i.e., light green, light purple, purple, dark purple and black. The content of total phenolics, soluble solids content (SSC) and titratable acidity greatly varied in the range from 24 to 237 mg of gallic acid equivalent per 100 g fresh weight, 18.60 to 26.30 % and 0.16 to 0.47 % in local genotypes and studied cultivars. In general, total antioxidant capacities determined by two methods expressed higher values in the local fig genotypes compared with the cultivars. The results suggested that genotype is the main factor that determines difference in the composition of bioactive compounds in figs and provide information on putative health benefits locally grown genotypes.Öğe Diversity on color and phenolic compounds in apricot fruits(Springer, 2017) Gundogdu, Muttalip; Ercisli, Sezai; Berk, Selma; Kan, Tuncay; Canan, Ihsan; Gecer, Mustafa KenanTurkey dominate world apricot production for a long time sharing 23% of world fresh apricot production and the country also realizes 82% of the total dried apricot trade of the world. In this study, phenolic compounds and fruit skin color in eight apricot cultivars grown in Malatya province of Turkey and correlations between phenolic compounds and fruit skin color were determined. Among apricot cultivars, 'Wilson Delicious' was the most orange-colored fruit skin color. Pyrogallol and rutin were found to be predominant phenolic compounds for all cultivars. Pearson correlation coefficients between pyrogallol, catechol, chlorogenic acid, caffeic acid, epigallocatechin and b color values were found statistically significant (P < 0.01). 'Harcot' cultivar came into prominence because of high pyrogallol (1596.26 mu g g(-1)), catechol (119.89 mu g g(-1)), chlorogenic acid (281.44 mu g g(-1)), caffeic acid (167.86 mu g g(-1)) and epigallocatechin (132.46 mu g g(-1)) levels. Overall 'Ordubat' cultivar had the lowest phenolic compounds. Among the yellow-colored cultivars, 'Harcot' and 'Wilson Delicious' had the richest phenolic compounds among yellow and orange-colored cultivars, respectively.Öğe Fruit Weight, Total Phenolics, Acidity and Sugar Content of Edible Wild Pear (Pyrus elaeagnifolia Pall.) Fruits(Springer, 2015) Yilmaz, Kadir Ugurtan; Ercisli, Sezai; Cam, Mustafa; Uzun, Aydin; Yilmaztekin, Murat; Kafkas, Ebru; Pinar, HasanWild pear (Pyrus eleagnifolia) is a naturally grown species mainly in inner Anatolia and its edible small fruits are traditionally consumed by local peoples and are called Ahlat in Turkey. Its seedlings are also used as rootstock for commercial pear cultivars. In this study, we reported first time pomological characteristics and biochemical compositions in fruits of a wide number selected wild pears genotypes (Pyrus eleagnifolia Pall.) from inner Anatolia. The obtained results revealed that there were significant differences among wild pear genotypes for all analyzed parameters. Fruit weight, total phenolics, total acidity and total sugar contents of the fruits varied from 4.71 to 27.09 g, 42.79 to 119.14 mg GAE/100 g, 0.20 to 1.40 g/100 g and 8.36 to 19.31 g/100 g, respectively. Considering these values, it was concluded that naturally grown wild pears of Anatolia with their rich salubrious biochemical compounds could reliably be used as a food source for humans.Öğe Genetic Relatedness in Prunus Genus Revealed by Inter-simple Sequence Repeat Markers(Amer Soc Horticultural Science, 2009) Yilmaz, Kadir Ugurtan; Ercisli, Sezai; Asma, Bayram Murat; Dogan, Yildiz; Kafkas, SalihInter-simple sequence repeat (ISSR) markers were used to study the genetic diversity and phylogenetic relationships among 16 genotypes from subgenus Prunus (six genotypes from section Prunophora, seven genotypes from section Armeniaca and two plumcot genotypes, and one genotype from subgenus Cerasus) in Prunus genus. From the polymerase chain reaction amplifications with 20 ISSR primers showing polymorphism among subgenera and sections, 180 polymorphic ISSR bands were detected and polymorphism ratio ranged from 57% to 100%. Based on the unweighted pair group method with arithmetic mean (UPGMA) analysis and principal coordinate analysis (PCoA) using the Jaccard coefficient, a dendrogram and three-dimensional plot were constructed including genotypes in Prunus genus. Two main groups formed in the dendrogram; one of them (Cluster I) included Cerasus, whereas Cluster II included Prunus. Cluster II also divided into three subgroups, including sections Prunophora, Armeniaca, and plumcot. Both UPGMA and the PCoA demonstrated that Armeniaca genotypes had lower genetic variation and plumcot genotypes are closer to the plums than the apricots. The ISSR-based phylogeny was generally consistent with Prunus taxonomy based on molecular evidence, suggesting the applicability of ISSR analysis for genotypic and phylogenetic studies in Prunus genus.Öğe Organic acids, sugars, vitamin C content and some pomological characteristics of eleven hawthorn species (Crataegus spp.) from Turkey(Soc Biolgia Chile, 2014) Gundogdu, Muttalip; Ozrenk, Koray; Ercisli, Sezai; Kan, Tuncay; Kodad, Ossama; Hegedus, AttilaBackground: The Hawthorn (Crateagus sp.) mostly occurs around the temperate region of the world with a high number of species, producing a fruit with numerous beneficial effects for human health. The aim of the study was to determine organic acid and sugar contents in the fruit of a number of hawthorn species grown in Erzincan province of Turkey. Results: Citric acid was the predominant organic acid in all hawthorn species and C. pseudoheterophylla had the highest citric acid content (23.688 g/100 g). There were not statistically significant differences among hawthorn species (except C. atrosanguinea Pojark) in terms of fumaric acid content. C. pontica C. Koch had a higher content of vitamin C (9.418 mg/100 g) compared to other species. Fructose was the predominant sugar component in all species and C. monogyna subsp. monogyna Joiq had the highest fructose content (18.378 g/100 g). Conclusions: The high fruit quality of the studied species indicates the importance of this fruit in human nutrition as a natural source. The study revealed that there were differences in terms of fruit characteristics among hawthorn species and thus better quality hawthorn genotypes can be selected within the species. Hence, this study is considered to be a valuable reference for forthcoming studies. The high fruit quality of the studied species indicates the importance of this fruit in human nutrition as a natural source.Öğe Phenolic compounds and vitamins in wild and cultivated apricot (Prunus armeniaca L.) fruits grown in irrigated and dry farming conditions(Soc Biolgia Chile, 2014) Kan, Tuncay; Gundogdu, Muttalip; Ercisli, Sezai; Muradoglu, Ferhad; Celik, Ferit; Gecer, Mustafa Kenan; Kodad, OssamaBackground: Turkey is the main apricot producer in the world and apricots have been produced under both dry and irrigated conditions in the country. In this study, phenolic compounds and vitamins in fruits of one wild (Zerdali) and three main apricot cultivars ('Cataloglu', 'Hacihaliloglu' and 'Kabaasi') grown in both dry and irrigated conditions in Malatya provinces in Turkey were investigated. Results: The findings indicated that higher content of phenolic compounds and vitamins was found in apricot fruits grown in irrigated conditions. Among the cultivars, 'Cataloglu' had the highest rutin contents both in irrigated and dry farming conditions as 2855 mu g in irrigated and 6952 mu g per 100 g dried weight base in dry conditions and the highest chlorogenic acid content in irrigated and dry farming conditions were measured in fruits of 'Hacihaliloglu' cultivar as 7542 mu g and 15251 mu g per 100 g dried weight base. Vitamin C contents in homogenates of fruit flesh and skin was found to be higher than beta-caroten, retinol, vitamin E and lycopen contents in apricot fruits both in irrigated and dry farming conditions. Conclusion: The results suggested that apricot fruits grown in both dry and irrigated conditions had high health benefits phytochemicals and phytochemical content varied among cultivars and irrigation conditions as well. However, more detailed biological and pharmacological studies are needed for the demonstration and clarification of health benefits of apricot fruits.Öğe Phenolic compounds, bioactive content and antioxidant capacity of the fruits of mulberry (Morus spp.) germplasm in Turkey(Polish Soc Horticultural Sci, 2017) Gundogdu, Muttalip; Canan, Ihsan; Gecer, Mustafa K.; Kan, Tuncay; Ercisli, SezaiThe study was carried out in 2014 and 2015, and aimed to determine some important biochemical and antioxidant characteristics of the fruits of mulberry (Morus spp.) cultivars and genotypes found in Malatya (Turkey). Phenolic compounds (protocatechuic acid, vanillic acid, ellagic acid, rutin, quercetin, gallic acid, catechin, chlorogenic acid, caffeic acid, syringic acid, p-coumaric acid, o-coumaric acid, phloridzin and ferulic acid), organic acids, sugars, vitamin C and antioxidant capacity were analyzed in sampled fruits. The results showed that most of the biochemical content and antioxidant capacities of the cultivars and genotypes were significantly different from one another (p < 0.05). Among the phenolic compounds, rutin (118.23 mg 100 g(-1)), gallic acid (36.85 mg 100 g(-1)), and chlorogenic acid (92.07 mg 100 g(-1)) were determined to have the highest values for most of the fruit samples. Malic acid and citric acid were dominant among the organic acids for all the cultivars and genotypes except 44-Nrk-05. Glucose was measured as a more abundant sugar than fructose and sucrose in all samples. Antioxidant capacity, on the other hand, varied between 6.17 and 21.13 mu mol TE g(-1) among the cultivars and genotypes analyzed.Öğe Some selected physico-chemical characteristics of wild and cultivated blackberry fruits (Rubus fruticosus L.) from Turkey(Ars Docendi, 2009) Yilmaz, Kadir Ugurtan; Zengin, Yasar; Ercisli, Sezai; Serce, Sedat; Gunduz, Kazim; Sengul, Memnune; Asma, Bayram MuratIn this study, some selected physico-chemical properties such as fruit weight, fruit length, fruit width, total soluble solids (TSS), titratable acidity, TSS/acidity ratio, pH, total phenolic content, antioxidant activity and free radical scavenging capacity of 9 cultivated and 16 selected wild blackberry (Rubus fruticosus L.) genotypes grown in Turkey were investigated. The total phenolic content, antioxidant activity and free radical-scavenging capacity of blackberry cultivars and genotypes were determined by using Folin-Ciocalteu, beta-carotene bleaching and DPPH radical assays. The results showed that, average fruit weight and fruit dimensions were higher in cultivated blackberries than wild materials. However, TSS, acidity and pH values were higher in wild materials. The total phenolic contents of blackberry cultivars and wild genotypes were in a range of 584 (cv. Bartin) to 788 (cv. Chester) mg/100 g and 610 (Genotypr R2) to 1455 mg/100 g (Genotype R16), expressed as gallic acid equivalents (GAE), on afresh weight basis. Antioxidant activity of cultivated and wild growing blackberry fruits was found between 72.15 (cv. Arapaho)-89.75% (cv. Bursa 3) and 59.85 (R1)-87.42% (R10), respectively. The antioxidant activity of standard BHA was 85.07%. Different cultivars grown in same location consistently showed differences in antioxidant capacity. The results of this study outlines that the blackberry fruits tested are good sources of natural antioxidants.
