The substances extract from plants are present a positive impact on the environment. This study is to valorize two substances extracts from the  seeds of Ceratonia Siliqua L plant collected from the north of the Morocco: Vegetable oil and a biopolymer (Galactomannan).

First part of the study is focused on the extraction of the oil by two solvents (cyclohexane and hexane) and their characterization by the physicochemical parameters such as the refraction index, acidic index, iodic index, density, color and odour. The chemical composition was determined by the GC/MS. Then, a comparative study was investigate to identified which the best antioxidant agent. The best one was used as a corrosion inhibitor in the acidic rainwater solution to protect the archeological iron. The obtaind results show that the formulation based on the oil extract from the Ceratonia Siliqua L by cyclohexane has a good inhibition behavior against the acidic attack solution. The inhibition efficiency increase whith increasing inhibitor concentration and reach a maximum at 97% at 750 ppm.

The second part of this work was devoted to the isolation of the biopolymer in order to determine its rheological behavior, and then it was used as corrosion inhibitor for iron in 1M HCl and then was used as charges in an organic coating.

The ineffective inhibitory effect of galactomannan against iron corrosion in the medium simulated in acid rain, led us to enhance this efficiency by a synergistic effect between the latter and the FCSL formulation.

These studies were carried out using the gravimetric measurements, the electrochemical techniques such as the polarization curves and impedances spectroscopies diagrams completed by the SEM/EDS as surface analysis techniques.

The results was showed that the biopolymer and the formulation FCSL are an exellent inhibitors for archeological iron in acidic medium.
