Antioxidant activities, expressed as IC50 values using DPPH, FRAP and BCB assays, for AEAPR, MEAPR, BHT and quercetin.

Sample Extracts	Test
	DPPH (μg/ml)	FRAP (μg/ml)	BCB (μg/ml)
MEAPR	12.38 ± 0.25∗∗∗ ###	50.89 ± 1.25∗∗∗ ###	107.07 ± 4.14∗∗∗ ###
AEAPR	13.41 ± 0.67∗∗∗ ###	60.17 ± 4.48∗∗∗ ###	120.66 ± 3.61∗∗∗ ###
BHT	4.21 ± 0.08	7.09 ± 0.10	4.30 ± 0.33
Quercetin	1.07 ± 0.01	2.29 ± 0.10	0.95 ± 0.02

Values are the mean of three determinations ± SEM, ^∗∗∗p < 0.001 significantly different from the BHT group and ^###p < 0.001 significantly different from the quercetin group. DPPH, 2,2-diphenyl-1-picrylhydrazyl; FRAP, ferric reducing antioxidant power; BCB, β-carotene bleaching; BHT, butylated hydroxy toluene.
