Figure 5. Effect of incubation time on the antioxidant activity of EGCg.

Figure 5

EGCg (1 mM) was incubated for up to 21 days in pH 7.4 PBS at 37 °C before determining radical scavenging activity with the ABTS assay. The IC50 values were expressed as Trolox equivalents. * indicates a statistical difference between the sample and fresh EGCg.
