Determination of antioxidant capacities and chemical characteristics of pomegranate (Punica granatum L.) grown in the Siirt district

Abstract

In this study, we measured the concentrations of organic acids, phenolic compounds, sugars and vitamin C as well as the total antioxidant capacities of pomegranate genotype cultivars grown in the Siirt province of Turkey. Our analysis of organic acids found citric acid concentrations between 0.66-2.75 g/L and malic acid concentrations between 0.61-3.88 g/L. Our analysis of phenolic compounds found catechin concentrations between 0.88-2.96 g/L and chlorogenic acid concentrations between 0.04-0.43 g/L. Further analyses revealed fructose concentrations between 4.76-11.74 g/100 g and glucose concentrations between 2.98-8.43 g/100 g. In addition, the concentrations of vitamin C and the total antioxidant capacities contents ranged between 11.40-45.07 mg/L and 4.56-16.64 mmol/L, respectively.
