Abstract


Due to a better understanding of its positive effects on nutrition and health, consumer demands for sesame seeds and products have increased steadily in recent years. The aim of the study is to determine the total phenolic content belonging to 17 different sesame genotypes (with different seed color) and the antioxidant content by DPPH and ABTS methods. The total amount of phenolic substance varied between 1.99-6.81 mg GA/g, and the highest amount of phenolic content was obtained from the Libya genotype, while the lowest value was obtained from the Gaziantep-Oğuzeli genotype. While antioxidant activity values obtained according to DPPH method varied between 8.23 and 17.50 mg Trolox/g, antioxidant activity values obtained according to ABTS method ranged between 3.62 and 4.18 (mmol Trolox)/g. According to the correlation analysis, it was determined that there was a statistically significant and positive relationship between antioxidant capacities according to total phenolic content, DPPH and ABTS methods. However, no relation was found between the seed color and these properties.
