Values are presented as mean ± SD () which, with different letters (within column), are significantly different at .
¹DPPH free radical scavenging activity represented by IC₅₀ was expressed as μg/mL.
²FRAP was expressed as mM ferric reduction to ferrous in 1 g of dry sample.
³ABTS free radical scavenging activity was expressed as mg ascorbic acid equivalent antioxidant capacity (AEAC) in 1 g of dry sample.
