Total antioxidant capacity and DPPH scavenging activity of different extracts of C. aegyptiaca fruits.

Extracts	TAC (mg GAE/g DE)	DPPH IC50 (mg·mL−1)
n-Hexane	123.771 ± 2.011 c	0.054 ± 0.010 c
DCM	181.414 ± 3.044 b	0.050 ± 0.002 b
MeOH	253.394 ± 1.198 a	0.041 ± 0.001 a
Vit C	-	0.033 ± 0.001 a

Values expressed are means ± S.D (n = 3). TAC: total antioxidant capacity, GAE: gallic acid equivalent, DE: dried extract. IC₅₀ (mg·mL⁻¹): inhibition concentration at which 50% of the DPPH (2,2-Diphenyl-1-picrylhydrazyl) are inhibited. The differences were analyzed using Duncan and Tukey’s post hoc test for multiple comparisons with p < 0.05. a: strong significance, b: high modest significance, c: low significance.
