Antioxidant activity of MeOH extracts of C. sativa (Marrone di Roccadaspide) burs, leaves, and chestnuts evaluated by Trolox Equivalent Antioxidant Capacity (TEAC), 1,1-diphenyl-2-picrylhydrazyl (DPPH), and Ferric Reducing Antioxidant Power (FRAP) assays.

C. sativa MeOH Extracts	Free Radical Scavenging Activity (DPPH) EC₅₀ (µg/mL ± SD ^a) ^b	(TEAC) (mg/mL ± SD ^a) ^c	FRAP (mmol ferric sulfate/g ± SD ^a) ^d
burs	4.21 ± 0.01	3.03 ± 0.03	2.96 ± 0.02
leaves	3.06 ± 0.01	3.01 ± 0.02	1.48 ± 0.02
chestnuts	34.64 ± 0.01	0.57 ± 0.01	0.18 ± 0.02

^a SD: Standard deviation of three independent experiments. ^b Determined by DPPH test. ^c Determined by TEAC assay ^d Determined by FRAP assay.
