a, Means ± SD (standard deviation) (n = 3); means followed by the same letter within each column are not significantly different [LSD test, (p < 0.05)]. b, Data expressed as mM TE/g FW of fruits. c, Results were taken from the study of Erkan et al. [14] and recalculated as mM TE/g of standard. d, Positive control.
