Assay method of DPPH analysis capability as an antioxidant (antioxidant) oxidation reagent is 2, 2-diphenyl-1-picrylhydrazyl. Be the fast way Simple analysis of high precision, accuracy andThe principle of theDPPH radical is stable in the solvent (methanol) to repel the MLS final this solution is purple, which absorb light very wavelength 515-517 nm (nm)How to react when the DPPH • substances having antioxidant activity. The color of the solution changes to a yellow brown, compared to free Commander Mu antioxidant used as a standard example is the BHT, if it has the ability to resist oxidation. The intensity of the purple solution is decreased.
