Abstract :This study aims to determine the antioxidant activities of fruit, leaf, and branche extracts of Morus alba L. and Morus nigra L. species collected from Diyarbakır. Different in vitro methods such as Total Phenol Content insert ignore into journalissuearticles values(TPC);, Total Flavonoid Content insert ignore into journalissuearticles values(TFC);, Copper insert ignore into journalissuearticles values(II); Ion Reducing Antioxidant Capacity insert ignore into journalissuearticles values(CUPRAC);, 2,2´-diphenyl-1-pikrilhidrazil insert ignore into journalissuearticles values(DPPH);, and 2,2`-azino-bisinsert ignore into journalissuearticles values(3-ethylbenzothiazoline-6-sulfonic acid); insert ignore into journalissuearticles values(ABTS); radical scavenging methods were used to evaluate the antioxidant activities of the two Morus species. The highest total phenolic amount belongs to acetone extract insert ignore into journalissuearticles values(257.5±0.05 μg gallic acid equivalent mg-1); obtained from M. nigra branches, while the highest total flavonoid content was found in acetone extract insert ignore into journalissuearticles values(185.8±0.15 μg catechin equivalent mg-1); obtained from M. nigra leaves. In the CUPRAC test, the highest activity was observed in methanol extracts from M. alba branches insert ignore into journalissuearticles values(IC50 values is 35.63±0.22 μg mg-1);. The IC50 values of the DPPH radical scavenging activity of the extracts are between 128.1±0.13 and 2494.7±0.30 μg mg-1, the best radical scavenging activity was demonstrated by acetone extract insert ignore into journalissuearticles values(128.1±0.13 μg mg-1); prepared from the M. alba branche. The highest ABTS radical scavenging activity belongs to the methanol extract insert ignore into journalissuearticles values(75.5±0.25 μg mg-1); obtained from the M. alba branches. The results prove that both Morus species possess antioxidant properties, not only in leaves and fruits but also in the branches. At the end of the study, it was determined that M. alba and M. nigra have medicinal usage value which can be used as natural antioxidants.
