Abstract

This review initiative had explored the applicability of the extract isolated from various plant parts of Sapindus (S.) species as the potential green corrosion inhibitor (GCI). Additionally, insights on topics like plant extracts in broad, concept of corrosion inhibition by the pool of biomolecules, use of (S.) species plant parts as the extract to retard corrosion of metals/alloys, composition of (S.) species extract, extraction techniques, etc were also covered. This article would form a platform to establish the present global status of (S.) species towards corrosion inhibition filed and related sectors (surfactant based). The favorable functional groups featuring in the biomolecules (having maximum hydrophilic part) along with the dominant inhibitor component (saponins) present in the (S.) extract had assisted the effective inhibition of corrosion in metals/alloys. This behavior of the extract (having the pool of biomolecules) can be attributed to various factors like superior adsorption, firm complexation and impermeable layer development over the surface of metal/alloy. This review initiative can promote the use of (S.) extract in commercial scale to retard the corrosion of various metals/alloys and hence can add financial angle for the cultivators.
