MetadataShow full item record
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.
