Assay	S. apiana	S. farinacea var. Victoria Blue	Standard
Assay	S. apiana	S. farinacea var. Victoria Blue	AA	BHA	Trolox
DPPH•	13.3 ± 1.1 ^a	17.4 ± 5.5 ^a	6.7 ± 0.7 ^b
Ferric reducing power	55.0 ± 5.6 ^a	59.9 ± 3.6 ^a		16.1 ± 2.0 ^b
TBARS	2.79 ± 0.1 ^a	42.2 ± 0.6 ^b			23.0 ± 1.0 ^c
β-carotene bleaching inhibition	41.2 ± 1.6 ^a	153.5 ± 2.2 ^b			41.7 ± 0.3 ^a

AA: Ascorbic acid; BHA: butylated hydroxyanisole; DPPH: 2,2-diphenyl-1-picrylhydrazyl; TBARS: thiobarbituric acid reactive substances. EC₅₀: half maximal effective concentration, corresponding to 50% of extract antioxidant activity or 0.5 of absorbance in ferric reducing power assay. Means followed by the same letters in rows do not differ according to Tukey’s test (p < 0.05).
