Phenolic acids, flavonols, anthocyanins and antiradical activity of “Nero”, “Viking”, “Galicianka” and wild chokeberries

Chokeberries are a subject of numerous studies due to a high phenolic compound content, antioxidant properties and potential positive influence on the health. In this work, phenolic compounds and the antiradical activity of three chokeberry cultivars (“Nero”, “Viking”, “Galicianka”) and wild chokeberries were compared during two consecutive year. The phenolic compound profile determined by high performance liquid chromatography (HPLC) was the same in all chokeberries. But some differences were found in the content of phenolic compounds. The total phenol and total anthocyanin content was higher in cultivars “Viking” and “Nero”. Cultivar “Galicianka” had the lowest phenolic compound content. The flavonol content was similar in all chokeberries. Phenolic acid content was high in wild chokeberries and in cultivar “Viking”. The antiradical activity was the strongest in wild chokeberries and in cultivar “Viking”. Wild chokeberries differed from other investigated chokeberries by somewhat higher amount of phenolic acids which might affect their antiradical activity.

► Chokeberry cultivars “Nero”, “Viking”, “Galicianka” and wild chokeberries showed differences in the phenolic compound content and in the antiradical activity.
► Differences were seen during two consecutive year.
► Phenolic compound content was high in Viking and Nero, low in Galicianka.
► Wild chokeberries were rich in phenolic acids.
► Phenolic acids might have influence the antiradical activity of some chokeberries.
