Mass loss technique has been used to study the corrosion inhibition efficiency of mild steel in HCl solution by using the stem, fruit and root extract of Leptadenia pyrotechnica. The results show that all the extracts under study are good corrosion inhibitors, among which stem extract is the most effective. Corrosion inhibition efficiency increases with increasing concentration of inhibitor and it also increases with increasing concentration of HCl solution. Inhibition efficiency was found maximum up to 93.07% for mild steel with 0.8% stem extract.
