DPPH assay as a method of analysis of the ability of a substance to resist oxidation (antioxidant), which uses a reagent is 2, 2-diphenyl-1-picrylhydrazyl is a convenient way quickly. Easier analysis, high precision and accurate
master
.DPPH radical is stable in methanol solvent (methanol) in aqueous solution are purple, which absorb light at the wavelength 515-517 NM. (Nm)
method.When the reaction is made 321 antioxidants. The color of the solution turns yellow to purple by comparison with independent Commander Mu antioxidant used as a standard, if there are, for example, 123 is the ability to resist oxidation, high.
