Abstract: This work summarized the study of the corrosion inhibition of volatile oils plant Qudneya africana.R.Br and the Zygophlum album L on carbon steel XC70, corrosion in acidic solution (H2SO4,1M) in the absence and the presence of demper in order to calculate the velocity of corrosion and them find the damping yield. And we used in this study the method of loss in mass. The oil extract wasobtained by two methods, the first by a soxley boiler, and the second by extraction by evaporation of the solvent by hexane and using them with different volumetric concentrations ranging between 3ppm and the 24ppm. The results obtained gave a closeness between the inhibitors in terms of yield values. The highest inhibition rate was for camel henna oil at 12ppm and aqah oil 21ppm and the mixture between them at 9ppm . In gesseral, the oils extracled from the two plants gave good protection and cambe classified as cathodic inhibitoss in the acidic medium H2SO4 and in various media. We also used modeling the results in R language on the two variables conceutration and yield, where we touched on the statistical values such as the arithmetic mean, standard deviation, regression straight, variance, chi-square x 2 to find the relationslip between them.
