Different letters in the same column indicate significantly different results (p ≤ 0.05; ANOVA, followed by S–N–K).
nq = not quantifiable for LOQ (iberin, 3.39 × 10−9 mol/mL; sulforaphane, 4.46 × 10−9 mol/mL; and erucin, 5.42 × 10−9 mol/mL).
nd = not detectable for LOD (iberin, 1.02 × 10−9 mol/mL; sulforaphane, 1.34 × 10−9 mol/mL; and erucin, 1.63 × 10−9 mol/mL).
