Values represent mean ± standard deviation of three biological replicates and three or more technical replicas. Different letters indicate a significant difference among the values in a row (ANOVA, Duncan’s test, p ≤ 0.05). TP = total phenolics; TF = total flavonoids; TFlo = total flavonols; THCA = total hydroxycinnamic acids; TPA = total phenolic acids; TA = total anthocyanins; GLS = total glucosinolates; PROT = total proteins; SS = total soluble sugars; GAE = gallic acid equivalents; QE = quercetin equivalents; CAE = caffeic acid equivalents; C-gluE = cyanidin-3-glucoside equivalents; SINE = sinigrin equivalents; BSAE = bovine serum albumin equivalents; SUCE = sucrose equivalents.
