Values are means of three determinations ± standard deviation. Values in the same row with the different superscript lowercase letters are statistically different (p < 0.05). a—p ≥ 0.05; b—0.005 < p < 0.05; c—p < 0.005; d—not compared; The results were compared to those received for C. mas. Anthocyanin contents were expressed as µg of cyanidin-3-glucoside per one mL. nd—not detected
