Figure 1.

The 2,2-diphenyl-1-picrylhydrazyl radical scavenging capacity of FEM. The absorbance values were converted to scavenging capacity (%) and data were plotted as the mean of replicate scavenging capacity (%) ± standard deviation (n = 3) against extract concentration in mg extract per ml reaction volume. Linear regression analysis was used to calculate IC₅₀ value
