Content of Bioactive Components in Chosen Cultivars of Cranberries (Vaccinium vitis-idaea L.)

Abstract

The of relation between chosen macro- and microelements, total polyphenol (TP) and anthocyanin content (TA) and antioxidant capacity (TAC) in 6 selected cultivars of cranberries (Sussi, Linnea, Sanna, Runo Bielawski, Ida, Koralle) is the aim of this study. The influence of cultivars on macro- and microelements content was confirmed. The Mg content was in interval 478.3–555.2 mg/kg, K 5690–7690 mg/kg, Fe 10.7–29.3 mg/kg, Cr 0.5–0.8 mg/kg, Cu 3.5–5.0 mg/kg and Zn 8.1–9.8 mg/kg. The lowest Mg, Cr, and Cu contents were determined in cultivar Ida with the highest TP and TA contents. TA contents in observed cultivars were in interval 221.778–498.503 mg/kg, TP contents 1394.32–1605.62 mg/kg TAC 63.58%–68.13%. The statistically significant differences of all observed parameters among cranberry cultivars (P < 0.05) were confirmed. Also the positive correlations of TAC and TP as well as TA contents were significant. TP content is in the positive correlation with TA content.
