Kinetics of the absorbance changes in DPPH• solutions in the presence of various concentrations (0.5–10.0%) of water-glycerine extracts of R. nigrum L. (A), V. myrtillus L. (B), R. fruticosus L. (C), and F. vesca L. (D). Values are mean of three replicate determinations (n = 3) ± SD. Negative control is: 0.25% ethanol solution.
