Capparidaceae (Capparis spinosa), is a common perennial shrub and woody plant, typically Mediterranean, largely used in folk medicine in the Mediterranean countries including Morocco. The effect of Capparis Spinosa (CSE) on the corrosion inhibition of carbon steel in 1 M hydrochloric acid (HCl) solution was evaluated by several analytical methods, among these are weight loss method, potentiodynamic polarization and impedance spectroscopy (EIS).

Results showed that CSE inhibits the corrosion of steel and the inhibition is more efficient at high concentration of CSE. Results also showed that, the inhibition decrease at higher temperature. Potentiodynamic polarization studies clearly reveal that CSE acts as a cathodic inhibitor. The adsorption of Capparis Spinosa on carbon steel was found to obey the Langmuir adsorption isotherm. The activation energies and enthalpies of the corrosion process of carbon steel in acidic medium of CSE were also calculated.
