Sample	TPC a	TFC b	DPPH c	ABTS d	FRAP e	O2− f (%)
Pulp	45.44 ± 0.67	35.57 ± 0.86	487.11 ± 26.22	190.32 ± 6.23	169.08 ± 9.81	76.46 ± 3.18 b
Seeds	37.21 ± 0.45	28.32 ± 0.35	354.51 ± 34.16	140.49 ± 3.58	147.84 ± 4.35	67.02 ± 2.23 b

^a Total phenolic content (TPC), expressed in mg of gallic acid equivalents per gram of dry plant. ^b Total flavonoid content (TFC), expressed in mg of quercetin equivalents per gram of dry plant. ^c 1,1-diphenyl-2-picrylhydrazyl radical (DPPH), as μmol of Trolox equivalent/g dry fruit, ^d ABTS as μmol of Trolox equivalent/g dry fruit. ^e Ferric reducing antioxidant power (FRAP), as μmol TE/g dry weight. ^f Superoxide anion scavenging activity (O₂⁻) expressed in %. All values were expressed as means ± SD (n = 3). The results are statistically compared with a positive control. The results were analyzed using one-way analysis of variance (ANOVA) and Tuckey test statistical analysis (p-values < 0.05 were regarded as significant). Values in the same column marked with the same letter are not significantly different (at p < 0.05).
