Also, the content of microelements and macroelements in the juice, pomace and fruit of Cornelian cherry were investigated. In the studied Cornelian cherry samples, the content of phenols ranged from 159.57 to 244.93 mg GAE/100 g, flavonoids from 71.74 to 165.5 mg QE/100 g, tannins from 0.33 to 0.81%, and total anthocyanins 0.057-0.310%. HPLC analysis identified the following anthocyanins: delphinidin-3-O-glucoside, cyanidin-3-O-galactoside, cyanidin-3-O-glucoside, pelargonin-3-O-glucoside and its derivative. The most abundant essential microelement in the studied Cornelian cherry samples was Fe (23.44-37.69 mg/kg), followed by Zn (3.14-6.25 mg/kg), Cu (1.50-1.80 mg/kg) and Mn (0.58-0.78 mg/kg). The most abundant essential macroelement in the examined samples was K (2427.8-3276.2 mg/kg), followed by Ca (361.5-475.7), Mg (95.41-146.5 mg/kg), and Na (8.347-16.59 mg/kg). Pb, Cd and Ni were not detected in the tested samples. A high degree of correlation was obtained between the content of total flavonoids and the antioxidant value measured by the FRAP method (R = 0.96), as well as between the content of total anthocyanins and antioxidant activity measured by the DPPH method (R = 0.89). Of the individual anthocyanins, high correlation values were shown by cyanidin-3-O-galactoside (R = 0.96), cyanidin-3-O-glucoside (R = 0.95) and pelargonin-3-O-glucoside (R = 0.94) with antioxidant activity measured by the DPPH method.
