TAILIEUCHUNG - Bioactive and antioxidant characteristics of blackberry cultivars from East Anatolia
Blackberry is commonly used both in the fresh and the processing market. In the present study antioxidant capacity, organic acids, phenolic compounds, vitamin C, and sugars content of blackberry cultivars grown in the east of Turkey were determined. | Turkish Journal of Agriculture and Forestry Turk J Agric For (2016) 40: 344-351 © TÜBİTAK doi: Research Article Bioactive and antioxidant characteristics of blackberry cultivars from East Anatolia 1, 2 1 Müttalip GÜNDOĞDU *, Tuncay KAN , İhsan CANAN Department of Horticulture, Faculty of Agriculture and Natural Sciences, Abant İzzet Baysal University, Bolu, Turkey 2 Department of Horticulture, Faculty of Agriculture, İnönü University, Malatya, Turkey 1 Received: Accepted/Published Online: Final Version: Abstract: Blackberry is commonly used both in the fresh and the processing market. In the present study antioxidant capacity, organic acids, phenolic compounds, vitamin C, and sugars content of blackberry cultivars grown in the east of Turkey were determined. Phenolic compounds, organic acids, vitamin C, and sugars were determined by HPLC. Antioxidant capacity was determined by spectrophotometric methods. The cultivar Cherokee had the highest antioxidant capacity ( µmol TE g–1), and the cultivar Jumbo had the lowest antioxidant capacity ( µmol TE g–1). It was determined that the chief phenolic compounds in blackberry cultivars were catechin (ranging from to mg 100 g–1), followed by ellagic acid (ranging from to mg 100 g–1). Looking at the content of organic acids, citric acid and malic acid came to the fore, ranging from to g kg–1 and to g kg–1, respectively. Fructose content of the studied cultivars was higher than the glucose and sucrose contents. Results indicate that blackberry cultivars with higher antioxidant capacity and biochemical content may be valuable for nutritional breeding efforts. Key words: Antioxidant, chemical diversity, phenolic compounds, organic acids 1. Introduction Horticulture is concerned with plants that are used by people for food (edible products and culinary .
