Twelve different morphometric parameters of the trees were investigated. The results showed significant differences between the pods of the three regions for most parameters (p = 0.05). The pods and the seeds of the north are thicker, longer and wider for apical, median and basal width and hereby a mass of seeds per pod which are important. The differences between the trees in the three regions showed a clear separation of the northern region of Morocco from the two other regions. Phytochemical study for flavonoids and saponins in the pulps of the trees showed a significant difference between the three regions. However, the difference for total phenols was not significant. The carob pulp o...

The extract was found to inhibit the corrosion of C38 steel in 1 M HCl. Results: The results of the study reveal that the inhibition efficiency of CO depends on its concentration and attains approximately 86.7% at 0.5 g/L. Polarization curves reveal that CO is a mixed-type inhibitor. Changes in impedance parameters (charge transfer resistance, R t , and double-layer capacitance, C dl) were indicative of CO adsorption on the metal surface, leading to the formation of a protective film. The effect of temperature on the corrosion behavior with the addition of 0.5 g/L of carob seed oil was studied in the temperature range of 298 to 328 K. Conclusions: Results show that the inhibition efficiency of the plant extract increases with increasing temperature, and the adsorption of the latter on the C38 steel surface is found to obey the Langmuir adsorption isotherm. Some thermodynamic functions of dissolution processes were also determined.
