Corrosive effect of Seed extract of Lablab purpureus (LLP) was investigated using phytochemical screening, weight loss technique, surface morphological analysis and quantum chemical studies. Influence of bioactive compounds in LLP extract contributes for adsorption properties towards mild steel (MS). The maximum inhibition efficiency of LLP extract was 97.98 % in 1N HCl for immersion period of 5h at 2.5 % v/v. SEM analysis established formation of protective layer on mild steel surface. Inhibition efficiency was found to increase with increasing concentration of LLP extract at room temperature. Results from various studies show that LLP can serve as an efficient inhibitor for corrosion prevention of mild steel in 1N HCl medium. Inhibition action may be contributed by the products of hydrolysis of active constituents of seed extract
