Antioxidant capacity, phenolic compound content, and mineral composition of ethanol extracts from sorbus aucuparia and sorbus kusnetzovii

Ethanol extracts of Sorbus aucuparia L. and Sorbus kusnetzovii Zinserl. fruits, belonging to the Rosaceae family, were obtained using an ultrasonic-assisted extraction method. The total phenolic contents of S. aucuparia and S. kusnetzovii were 8.44±0.66 mg GAE/g and 8.65±2.18 mg GAE/g, respectively, while their total flavonoid contents were 2.30±0.01 mg QE/g and 2.67±0.13 mg QE/g, respectively. The fruits’ DPPH values were measured as 9.59±0.00 mg TE/g and 9.28±0.05 mg TE/g, FRAP values as 9.51±0.42 mg TE/g and 13.38±0.52 mg TE/g, and CUPRAC values as 13.43±0.01 mg TE/g and 23.21±0.74 mg TE/g. Furthermore, both Sorbus species were found to have a rich mineral content. Therefore, it can be concluded that S. aucuparia and S. kusnetzovii fruits contain potent antioxidants, abundant phenolic compounds, and valuable minerals. Furthermore, they have significant potential as functional foods and are strong candidates for further clinical research.
