TPC: total phenolic content; TMA: total monomeric anthocyanins. Mean values ± SD, n = 3. Values preceded with the same capital letters (A–C) within the same row of a given table are not statistically different (α ≤ 0.05). Within a given cultivar and phenolic determination method, values followed with the same lowercase letters (a–c) within the same column of a given table are not statistically different (α ≤ 0.05).
