- +EC50 (mg/mL): effective concentration at which 50% of ABTS radicals are scavenged
- ++EC50 (mg/mL): effective concentration at which the absorbance is 0.5
- +++EC50 (mg/mL): effective concentration at which the total antioxidant activity (TAA) was 50%
- Effect of Trolox or Ascorbic acid used as standards, were measured in the same conditions than the RaEO. All experiments were performed in triplicate and the results were expressed as the mean ± standard deviation (SD). Statistical comparisons were performed through an unpaired Student’s t-test using GraphPad InStat version 3.0a for MacIntosh
