The aim of this article is to study the Eugenia Caryophyllata extract (ECE) like a green corrosion inhibitor of steel in 1 M hydrochloric acid solution (HCl). The extract was obtained by hydro-distillation and then it was characterized by gas chromatography coupled with mass spectroscopy (GC/MS). Its efficiency was evaluated by electrochemical measurements (linear polarization resistance (LPR.
