a DPPH free radical scavenging was expressed as mg ascorbic acid equivalent antioxidant capacity (AEAC) in 1 g of dry sample; b ABTS decolorization assay was expressed as mg ascorbic acid equivalent antioxidant capacity (AEAC) in 1 g of dry sample; c FRAP was expressed as mM ferric reduction to ferrous in 1 g of dry sample.
