Corrosion inhibitors are widely used in many industries to reduce the corrosion of metals and alloys in contact with a corrosive environment. Most corrosion inhibitors are synthetic organic and inorganic chemicals, expensive, and very hazardous to the environment. Green inhibitors for protection of metals and alloysare of good alternative of synthetic chemical inhibitors. Natural occurring compounds are a good source of green corrosion inhibitors, where most of their extracts containing fictional groups along with hetero-atoms which are active in green compounds, assist in adsorption of these compounds on metal surfaces to form a barrier that protects the metallic surface and retards corrosion process.Development of green chemistry and green chemical technologies offers novel synthetic methods for the development new generation compounds which are considered as new green corrosion inhibitors. In this review briefly discuss the potential of various plants extract as a green corrosion inhibitor on metal surfaces like aluminium, mild steel, carbon steel, stainless steel, copper and zinc in corrosive environment by weight loss, potentiodynamicpolarisation, gravimetric techniques. The inhibition efficiency has also been discussed in detail. This study will further support in the understanding of the mechanism of adsorption involved in inhibition and explore inhibition property of plant extract against metal deterioration.
