Ferric Reducing Antioxidant Potential Assay (FRAP Assay).
Correlations and regression analysis between the antioxidant activities of the three independent tests (FRAP, HRSA, and LPIA) and contents of secondary metabolites, including TPC, TAC, and TSC were conducted using the regression program in SPSS 13.0.
The new version handles all FRAPS recordings, even in high definition, and lets you add music to your cut.

The ferric reducing-antioxidant assay (FRAP) is based on the reduction at low pH of ferric 2, 4, 6-tris(2-pyridyl)-1,3,5-triazine [Fe(III)-TPTZ] to the ferrous complex followed by spectrophotometric analysis [1].
