Two indigenous species of Mentha: M. viridis L. var. crispa (Schard.) Briq. and
M. longifolia (L.) Huds. were studied in order to evaluate the phenolic profile and the
natural antioxidant capacity. The polyphenolic content was determined by using the Folin-
Ciocalteu reagent. The antioxidant activity was evaluated using 2,2-diphenyl-1-
picrylhydrazyl (DPPH) radical scavenging assay. The determination of polyphenolic
compounds was performed by HPLC-MS. In M. viridis var. crispa. aerial parts extract the
phenolic acids were predominant, while in M. longifolia extract, the flavonoids were
majoritary. These two extracts contain a large amount of phenolic compounds, and show
moderate antioxidant activity.
