Inhibition of Chrysophyllum albidum leave (CAL) extract toward 0.5 M H2SO4 corrosion of aluminium was optimized applying response surface methodology. Corrosion analysis was carried out using weight loss and electrochemical techniques. The results of the various analyses of the leave extracts acted as a good corrosion inhibitor for aluminium in 0.5 M H2SO4. Inhibition efficiency increases as the extract concentration increased. Results of molecular dynamic simulations of the active constituents of the extracts confirmed the adsorption potentials of the ethanol extracts of CAL. Optimal inhibition efficiency of 78.43(%) was obtained at optimum inhibitor concentration of 1.00 g/l, 11.71hs and temperature of 303.60k.
