Table 4 Absorbance of test solution at different concentrations of samples in the reducing power assay (700 nm)

From: Comparative study of the antioxidant and antibacterial activities of Rumex abyssinicus with commercially available Zingiber officinale and Curcuma longa in Bahir Dar city, Ethiopia

Concentration (%v/v)	Absorbance
Concentration (%v/v)	RA	ZO	CL
24.00	0.187 ± 0.008	0.058 ± 0.001	0.054 ± 0.001
32.00	0.259 ± 0.004	0.073 ± 0.002	0.066 ± 0.004
40.00	0.323 ± 0.004	0.089 ± 0.002	0.083 ± 0.004
48.00	0.396 ± 0.016	0.108 ± 0.002	0.100 ± 0.003

Data are expressed as mean of three determinations ± SD. There was a significant difference in the mean absorbance of the samples (p < 0.05)
