Correlation analysis between ferric-reducing antioxidant power, Trolox equivalent antioxidant capacity, total phenolic content, and total flavonoid content values

Correlation Coefficient (R2) FRAP value (μmol Fe2+/g DW) TEAC value (μmol TE/g DW) TPC value (mg GAE/g DW) TFC value (mg QE/g DW)
FRAP value 1 0.9340 0.9600 0.9139
TEAC value - 1 0.9013 0.8729
TPC value - - 1 0.8829
TFC value - - - 1

DW: Dried weight; FRAP: Ferric-reducing antioxidant power; GAE: Gallic acid equivalent; TE: Trolox equivalent; TEAC: Trolox equivalent antioxidant capacity; TFC: Total flavonoid content; TPC: Total phenolic content; QE: quercetin equivalent.
