Ferric reducing antioxidant power of Trachyspermum ammi L. seed extracts (AASE: ajwain aqueous seed extract, AMSE: ajwain methanolic seed extract, and AAcSE: ajwain acetonic seed extract) compared with BHT (butylated hydroxytoluene) as standard antioxidant at different concentrations (0.2–1 mg/mL) in terms of FRAP value expressed in µmol/L. Statistical significance was determined using Student's t-test. P value < 0.05 was considered as significant (**= significant and ***= highly significant).
