Abstract:	The corrosion resistance of Cissus quadrangularis in acid and ethanol medium have been investigated by diverse techniques. It has been noticed that as the concentration (2 to 12v/v %) of C. quadrangularis rises the efficiency of the inhibitor also increases. The maximum inhibition efficiencies of 89.45 % and 75.54 % were attained for acid and ethanol extracts respectively. The emergence of a protective layer on the mild steel surface was assessed by electrochemical impedance studies. The influence of the active ingredients in the extracts was examined by GC-MS analysis. The inhibitor adsorption ensued in the protective layer on the surface was analyzed using SEM and AFM.
