Accession values represent triplicate means ± standard errors from the mean; population variability is indicated by the grand mean and its associated coefficient of variability (i.e., the population standard deviation expressed as a percentage of the mean). TP content was estimated by the Folin-Ciocalteu assay of Singleton and Rossi.[21] Values are expressed as micrograms of gallic acid equivalents/g fw. TMAs were determined by the pH-differential method of Giusti and Wrolstad.[22] Values are expressed as micrograms of cyanidin 3-glucoside equivalents/g fw. FRAP values were determined by the method of Benzie and Strain.[24] Values are expressed as micrograms of trolox equivalents/g fw. DPPH values were determined by the method of Brand-Williams et al.[25] Values are expressed as micrograms of trolox equivalents/g fw. TA was determined by the titration method of Perkins-Veazie and Collins.[20] TSSs were determined by refractometry
