Antioxidant activities of 3 types of Dictyophora indusiata aqueous extracts.

Sample	DPPH Scavenging Activity (SC50, mg/mL)	ABTS Scavenging Activity (SC50, mg/mL)	Metal Chelating Activity (MC90, mg/mL)	FRAP Reducing Power (µM Fe2+/g Extract)
PGW	2.51 ± 0.05 *	8.52 ± 0.09	32.18 ± 0.23 *	6.18 ± 0.08
CW	1.54 ± 0.02 *	6.51 ± 0.08	5.11 ± 0.45 *	2.13 ± 0.09
WW	3.59 ± 0.02 *	11.81 ± 0.09	34.58 ± 0.39 *	3.00 ± 0.03
EDTA	Nd	Nd	0.10 ± 0.09	Nd
L-ascorbic acid	0.26 ± 0.02	Nd	Nd	Nd

Each value is expressed as mean ± SD (n = 3); peel and green mixture (PGW); core (CW); whole (WW). Ethylenediaminetetraacetic acid (EDTA); SC₅₀ = the concentration providing 50% scavenging activity (mg/mL); MC₉₀ = the concentration providing 90% chelating activity (mg/mL); µM Fe²⁺/g extract = µM of ferrous ion per g of extract; Nd = Not determined. Significant differences are indicated as * p < 0.05 (compare to the standard substances).
