This paper presents a comparative study about the evaluation of antioxidant activity and corrosion inhibition in Kenitra, Marrakesh and Taiz. An interesting topic, indeed polyphenols can improve or help to reduce oxidative stress in the treatment of digestive problems, weight management difficulties, diabetes, hypertension, arteriosclerosis and damage fatty tissue. Therefore, the authors deal with the measurement of polyphenol content and evaluation of the antioxidant activity of lemon peels in Kenitra , Marrakesh and Taiz.The authors performs empirical analyzes on lemon peels. The total polyphenol contents of the ethanolic extract of lemon peels were measured. It was to be 30. 23, 26. 346 and 20.961 mg/CE/g in Kenitra, Marrakech, and Taiz, respectively. Moreover, the DPPH radical scavenging activity of ethanolic extract of dried lemon peels was higher than 200μg/ml concentration. They were 73.47%, 47.36%, and 32.09in Kenitra, Marrakech, and Taiz, respectively. Also, the IC50 values of ethanolic extracts calculated from the percentage inhibitions at the same concentration. Inhibition (IC50) which obtained in Kenitra was 123.089 μg/ml. It was lower compared to the ethanol extract of Marrakech and Taiz that were 197.418, 276.750μg/mL, respectively. Therefore, the extract which is containing a high amount of phenolic is showed high radical scavenging activity. In addition, the maximum inhibition efficiencies for 2 mL L-1 of the inhibitor at 298 k were 98, 12% and 84, 85 % in Kenitra and Taiz, respectively. These values obtained through polarization curve measurements.
