Evaluation of the effect of Mentha extracts on cells growth by phase contrast microscopy. The extracts from three Algerian Mentha species, M. spicata L. (MS), M. pulegium L. (MP), and M. rotundifolia (L.) Huds (MR) used at final concentrations of 25, 50, 100, 200, and 400 μg/mL were evaluated on murine RAW264.7 macrophage cells by phase-contrast microscopy after 48 h of treatment. Data shown are representative of at least three independent experiments. 7-Ketocholesterol (7KC; 20 μg/mL) was used as the positive control; vehicle control for 7KC corresponds to ethanol (0.1%).
