Table 1. Antioxidant activities of hydroalcoholic extract of saffron. Results are expressed as means ± SD of triplicate (n = 3).

Assays	TPC (mg gallic acid equivalent/g DW)	IC50 of DPPH Radical Scavenging Activity (μg/ml)	FRAP (mmol Fe2+/g DW)
Hydroalcoholic extract of saffron	9.02 ± 0.69	189 ± 7.6	1.4 ± 0.21

The IC₅₀ values were calculated from linear regression analysis which indicates the effective concentration of samples used to reduce 50% of the reagent colour.
