Antioxidant activity of RGSE including DPPH radical scavenging activity, TEAC, FRAP, HRSA, SRSA, and FICP

	Antioxidant activity
	DPPH	TEAC	FRAP	HRSA	SRSA	FICP
RGSE	0.03 ± 0.01	395.65 ± 1.61	114.24 ± 0.03	5.40 ± 0.01	0.58 ± 0.01	3,474.05 ± 5.55
Ascorbic acid	0.01 ± 0.01	-	-	-	-	-
Trolox	-	-	-	2.16 ± 0.06	0.32 ± 0.01	-

Data are expressed as mean ± S.E.M, n = 3. DPPH radical scavenging activity, Hydroxyl radical scavenging activity (HRSA), and Superoxide radical scavenging activity (SRSA) are expressed as the IC₅₀ value (mg/ml). TEAC, FRAP, and FICP are expressed as mg trolox/gram dried extract, mM FeSO₄/gram dried extract, and mg EDTA/gram dried extract, respectively.
