Ferric ion-reducing antioxidant power and copper ion reductive capability of corn silk extracts of the silking stage (CS-S), the milky stage (CS-M) and the mature stage (CS-MS).

Corn Silk Sample	Ferric Ion-Reducing Power a	Copper ion Reductive Capability a
CS-S	1.33 ± 0.32 a	0.89 ± 0.09 a
CS-M	0.53 ± 0.11 b	0.78 ± 0.09 a
CS-MS	2.63 ± 0.15 c	1.21 ± 0.13 b

^a Data are expressed as the mean ± standard deviation of three replicates. Superscripts with different letters in the same column indicate significant differences between the samples (Tukey’s test, α ≤ 0.05).
