Antioxidant activity of ethanolic mint extracts using the Kit Radicaux Libres (KRL^TM), the ferric reducing antioxidant power (FRAP) and the 2,2-diphenyl-1-picrylhydrazyl (DPPH) assays.

Antioxidant Assays	Antioxidant Activity (mg of Trolox equivalent/g)
	MS	MP	MR
KRL	796.78 ± 2.72 a	554.19 ± 2.46 c	606.34 ± 1.09 b
FRAP	1430.13 ± 221.66 a	776.48 ± 39.48 b	364.79 ± 32.52 c
DPPH	207.96 ± 10.98 a	81.98 ± 6.44 b	38.50 ± 1.96 c

Data are presented in Trolox Equivalent (TE). Data shown are mean of three independent experiments realized in triplicate. Mentha spicata L. (MS), Mentha pulegium L. (MP) and Mentha rotundifolia (L.) Huds (MR). Values in the same line sharing different letters are significantly different (Mann Whitney, p < 0.05).
