abstract={This work aims to highlight the value of an aromatic and medicinal plant from the Errachidia region, <i><b>Anethum</b></i><i><b> </b></i><i><b>graveolens</b></i>. This study evaluates the inhibitory effect of essential oil extracted from the seeds of this plant on the corrosion of C38 steel in 1M HCl medium. The essential oil was extracted from seeds using a Clevenger apparatus, achieving an average yield of 3.5% via hydrodistillation. Characterization by chromatography (GC/FID and GC/MS) identified 12 constituents representing 98% of the oil's global composition, with carvone (43.5%), dillapiol (26.7%), and limonene (15.4%) being the main components. Gravimetric tests revealed a remarkable inhibitory effect on steel corrosion, with increased concentration and temperature achieving an inhibition efficiency of 82.54% at 0.5 g/L and 338 K. Thermodynamic parameters determined show that the inhibitor's adsorption on the metallic surface follows the Langmuir model. The results indicate a mixed adsorption behavior of this essential oil. DFT calculations correlate the inhibitory activity with the electronic properties of the main constituents of the essential oil.},
