Antioxidant Capacity and Bioactive Contents of Mulberry Species from Eastern Anatolia Region of Turkey

In this study, we aimed to determine biochemical contents of white (Morus alba L.) and black (Morus nigra L.) mulberry genotypes grown in the Hakkari region. At the end of the study, organic acids, phenolic compounds, sugars, vitamin C and antioxidant capacities of mulberry species were determined. Black mulberry genotypes were found to contain higher antioxidant capacity than white mulberry genotypes. The highest antioxidant capacity was detected in the 30YK03 (25.55 mu moITE/g) black mulberry genotype. While phenolic compounds varied in mulberry species, especially gallic acid (57.78 mg/100g), chlorogenic acid (53.13 mg/100g), and rutin (37.77 mg/100g) had the highest values. Malic acid was found to be higher than other organic acids and was found to be 13.51 g/100g in the highest 30HK03 genotype. Although sugar contents varied in mulberry species, glucose was determined higher than fructose and sucrose in mulberries.
