Table 4.

The IC₅₀ values indicating antioxidant activity of phenolic-enriched fraction (PEF) and positive control (gallic acid)

	IC₅₀ (μg/ml)
	DPPH scavenging activity	Reducing power activity	ß-carotene bleaching inhibition	TBARS inhibition
PEF	24.6^a	31.2^a	37.1^a	42.9^a
Gallic acid	4.6^b	7.4^b	11.6^b	14.5^b
S.E.M	0.82	0.79	1.27	1.12

All data are presented as means (± SEM) of at least three replicates (n = 3)

Means (n = 3) with different superscripts (a,b) within a column are significantly different (p < 0.05)

S.E.M Standard error of the means
