Fractions	DPPH (IC50 µg/mL)	FRAP (mmol Fe^2+/g extract)	FCA (IC50 µg/mL)	NORSA (IC50 µg/mL)
HF	ND	0.14 ± 0.01^a	93.75 ± 7.75^a	ND
CHF	ND	0.24 ± 0.01^b	314.55 ± 5.32^b	ND
EAF	33.65 ± 3.04^a	1.64 ± 0.06^c	165.45 ± 5.65^c	86.19 ± 3.83
WF	184.58 ± 7.31^b	0.20 ± 0.01*	ND	ND

Data are mean ± SE (𝑛=3). Means with different lower case letters (a, b, c, and d) in the same column are significantly different at P < 0.05 (ANOVA, followed by Dunnett’s multiple comparison test). *P < 0.05 compared to a and c in the same column. DPPH: 2,2 diphenyl-1-picrylhydrazyl. FRAP: ferric reducing antioxidant power. FCA: ferrous ion chelating activity. NORSA: nitric oxide radical scavenging activity. HF: n-hexane fraction. CHF: chloroform fraction. EAF: ethyl acetate fraction. WF: water fraction. ND: not detected.
