Inhibitors are known for their specificity of action.1 A substance, which effectively protects a given metal under certain conditions, may cease to be effective under other conditions or with other metals. The extracts of some common plants and by-products (peels, seeds, fruit shells, leaves, etc.) contain different organic compounds (e.g., amino acids, tannin, alkaloids, and most of their constituents), which are known to have inhibitive action.2-6 It is therefore expected that the essential oils extracted from plants would exhibit inhibitive action. Vapor corrosion inhibitors (VCIs) are chemicals that are used to protect metallic items from atmospheric corrosion during manufacture, storage, and transportation. Initially, camphor was used to protect military equipment and machinery parts.6 In later years, the development of organic compounds as VCIs for metals7- 10 has been important. Our previous work11-12 revealed that the extracts of bark oils and amine-azole-nitro compounds are quite effective in reducing the corrosion of mild steel in marine and industrial environments. Jasminum grandiflorum (JG), Jasminum auriculatum (JA), Oleum palmarosae (OP), Ocimum basilicum (OB), and Vetiveria zizanioides (VZ) oils were used in this work.
