Phenolic compounds and antioxidant capacities of bayberry juices

Abstract

Phenolic compounds and antioxidant capacities of bayberry juices from 14 cultivars were investigated. HPLC-DAD and Folin-Ciocalteu methods were used for the analysis of the phenolic compounds. Biqi had the highest content of total flavonols (56.75 ± 4.68 mg/l), Wuzi had the highest content of phenolic acids (30.1 ± 0.05 mg/l), and Lizhizhong had the highest content of anthocyanins (514 ± 46.1 mg/l) and total phenolics (1055 ± 9.32 mg GAE/l). The FRAP and ABTS{radical dot}+ assay indicated that bayberry juices possessed considerable antioxidant activities, and all the analysed phenolic components contributed to the antioxidant capacities. The results also showed that bayberry juices from red ..
