Figure 1

Contour graph showing effect of different variables on antioxidant potential (% activity) as assayed by different procedures (a) 1,1-diphenyl-2-picryl hydrazyl free radical (DPPH) assay (hold value: 0.05% of sodium nitrate); (b) reducing power (in absorbance) (hold value: 0.05% of sodium nitrate); (c) ferrous ion scavenging activity (hold value: 0.05% of sodium nitrate); (d) nitric oxide ion scavenging activity (hold value: 0.05% of sodium nitrate); (e) FRAP assay (hold value: 0.05% of sodium nitrate); (f) total phenolic content (mg/mL) (hold value: 0.05% of sodium nitrate).
