In this research, corrosion inhibitors were synthesized using locally available biomass, alfalfa plant. The inhibitor performance was evaluated at different operating conditions and the effect of process variables, namely inhibitor concentration (1-5%v/v), operating temperature (308.15-328.15 K) and method of extraction (alcohol and aqueous) were studied. The corrosion rate of aluminum decreased with increase in inhibitor concentration and the best result attained was 3.7mg cm-2 h-1 with 5%v/v AALE and 308.15 K. The increase in temperature resulted in the decrease in inhibition efficiency, which could be related to detachment of inhibitors at elevated temperatures. The Langmuir adsorption Isotherm fitted well to the corrosion experiment data (R2>0.990) and thermodynamic parameters were calculated. The value of separation factor (0
