  1. The results are presented in EC50 values, meaning that higher values correspond to lower reducing power, radical scavenging activity. EC50 is the concentration of the extract that corresponds to 50% of antioxidant activity for the ferrous ion-chelating, DPPH, hydroxy, and or 0.5 of absorbance for the ferricyanide/Prussian blue assays
  2. a,b,cIn each row, the different letters represent significant differences between samples (p < 0.05)
