The reducing power assay measures the electron-donating capacity of antioxidant using potassium ferricyanide reduction method (Hollman, 2001).
Before injection onto the column, samples were derivatized by addition of 50 [micro]L of freshly prepared potassium ferricyanide in 15% sodium hydroxide (Fig.
In turn, the hydrogen peroxide reacts with ferricyanide in a way that reduces that molecule's hunger for electrons.

1mL of extract solution at different amounts was mixed with 2.5 mL of 0.2 M phosphate buffer (pH 6.6) and 2.5 mL of 1% potassium ferricyanide. The obtained reaction mixture was then incubated in a water bath at 50[degrees]C for 20 min.
A concentration of sample under test (0.5ml intact cell cell lysate or extracellular secretions) was mixed with 0.5ml of 0.2M sodium phosphate buffer (pH 6.6) and 0.5ml of 1% potassium ferricyanide (w/v) and the resultant mixture was cooled rapidly after incubated at 50 for 20 min.
The dried extract (100-1000 [micro]g) in 1 ml of the ethanol 50%, was mixed with 2.5 ml of phosphate buffer (0.2 M, pH 6.6) and 2.5 ml of potassium ferricyanide [K3Fe (CN)6; 10 g/l], and incubated at 50[degrees]C for 30 min.
