Free radical scavenging activities and reducing power of EECP and EEPG.

Samplea	DPPH (IC50)	ABTS (IC50)	RP (mmol TE/g)	SRSA (mmol TE/g)	ORAC (mmol TE/g)
EECP	32.35NS ± 2.84	40.5** ± 2.38	2.08** ± 0.08	1.52** ± 0.03	9.25* ± 0.85
EEPG	31.83 ± 2.68	55.4 ± 1.49	1.55 ± 0.05	0.67 ± 0.02	6.43 ± 0.46

  ^aData are showed as the mean ± SD (n = 3); statistical analysis were used to compare EECP with EEPG for every index, separately. NS means not significant (P > 0.05); ^*means significant (P < 0.05); ^**means very significant (P < 0.01). DPPH and ABTS are expressed as IC50 (μg/mL); FRAP, SRSA, and ORAC are expressed as millimoles Trolox equivalents (TE) per gram of sample.
