Rice Germosprout Extract Protects Erythrocytes from Hemolysis and the Aorta, Brain, Heart, and Liver Tissues from Oxidative Stress In Vitro

Figure 2

Germosprout extract scavenged DPPH-free radical. The figure illustrates the ability of germosprout extract and gallic acid to scavenge DPPH-free radicals. Data are the representative of triplicate determinations. Data were subjected to nonlinear sigmoidal dose-response curve, , where is the logarithm of concentration. = the scavenging response. starts at the bottom and goes with sigmoid shape. Bottom = (0), top = (100%), and = the value of at -mid. In other words, IC50 is the concentration of antioxidants (here, gallic acid and germosprout extract containing antioxidants such as polyphenols) required to reach half-maximal scavenging of DPPH-free radical. GAE: gallic acid equivalent.
