The aim of this study was to investigate the protective effect of Mentha spicata supplementation against nicotine-induced oxidative damage in the liver and erythrocytes of wistar rats. Bioactive substances were determined by liquid chromatography-electrospray ionization-tandem mass spectrometry analysis. Animals were divided into four groups of six rats each: a normal control group, a nicotine-treated group (1 mg/kg), a group receiving M. spicata extract (100 mg/kg), and a group receiving both

After 2 months treatment, nicotine induced an increase in the level of white blood cells and a marked decrease in erythrocytes, hemoglobin and haematocrit. Aspartate transaminase, alanine transaminase, alkaline phosphatase and lactate dehydrogenase activities were also found to be higher in nicotine-treated group than those of the control one. Furthermore, nicotine-treated rats exhibited oxidative stress, as evidenced by a decrease in antioxidant enzymes activities and an increase in lipid peroxidation level in liver and erythrocytes. Interestingly, the oral administration of M. spicata extract by nicotine-treated rats alleviated such disturbances. M. spicata contained bioactive compounds that possess important antioxidant potential and protected liver and erythrocytes against nicotine-induced damage.
