DPPH and reduction power inhibition and EC₅₀ values of honey phenolic extracts and synthetic antioxidants

Extracts and synthetic antioxidants	DPPH inhibition EC50 (µg/mL)	% Inhibition of DPPH (200 µg/mL)	Reduction power (200 µg/mL) (Abs)
Center Honey Extract	97.26 ± 5.79*	54.08 ± 0.26**	0.19 ± 0.08*
Solhan Honey Extract	98.29 ± 8.43*	55.71 ± 0.33**	0.18 ± 0.06*
Yedisu Honey Extract	85.25 ± 6.56**	64.00 ± 0.81*	0.22 ± 0.03*
Adaklı Honey Extract	97.46 ± 9.79*	55.91 ± 0.47**	0.22 ± 0.04*
Karlıova Honey Extract	98.07 ± 7.89*	56.60 ± 0.72**	0.12 ± 0.08**
BHA	80.31 ± 9.91	61.40 ± 039	2.44 ± 0.09

Statistical analysis of DPPH inhibition EC50 and Reducing Power in honey phenolic extracts was done according to BHA standard antioxidant. Statistical analysis was performed with one-way ANOVA using Dunnett’s multiple comparison as a post test in the confidence interval of either P < 0.05 (*) or P < 0.001 (**). Values are expressed in mean ± SEM (n = 3)
