Figure 7. The free radicals scavenging activity of DPPH under the influence of nanoparticles synthesized by hydroalcoholic extract of polygonum aviculare L. in comparison with positive control of standard ascorbic acid in different concentrations. The comparison between AgNPs and ascorbic acid demonstrated a noteworthy difference, with a statistical significance of P < 0.005.
