Table 2 Absorbance of Prussian blue color at different concentrations of samples (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
10.00	0.119 ± 0.018	0.038 ± 0.014	0.095 ± 0.012
20.00	0.219 ± 0.017	0.063 ± 0.010	0.139 ± 0.010
30.00	0.310 ± 0.007	0.086 ± 0.003	0.177 ± 0.007
40.00	0.402 ± 0.006	0.110 ± 0.005	0.224 ± 0.011

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