n = 3. a–d Values in the same column followed by different superscripts indicate significant differences (p < 0.05). TPC = total phenolic content, ABTS = 2,2′-azino-bis-3-ethylbenzo-thiazoline-6-sulphonic acid, ORAC = 2 oxygen radical absorbance capacity, GAE = gallic acid equivalents, TE = trolox equivalents, w.s. = wet sample., d.s. = dry sample.
