Figure 10.
Dose-dependent ABTS (%) radical scavenging activity of E. foeminea crude extracts. (a) Acetone; (b) dichloromethane/methanol; (c) ethanol; (d) ethyl acetate; (e) methanol; (f) ascorbic acid as control. Pearson correlation coefficients (r) between concentrations and % radical scavenging activity were found to be 0.9735, 0.9969, 0.9970, 0.9988, and 0.9995, respectively. Values are the means of triplicate analyses; error bars denote the relative standard deviation.
