The Inhibition effect of plant extract of rosemary oil (Rosmarinus officinalis) on corrosion of high carbon steel in 0.5M citric acid and 3.5wt% sodium chloride had been done by weight loss method. 0%, 0.50%, 1.00%, 1.50%, 2.00% and 2.50% concentration of rosemary oil was used on sodium chloride and citric acid solutions. Results from weight loss analysis shows that rosemary oil performed more strongly in sodium chloride solution compared to citric acid with excellent inhibition efficiency of 97.86% at 2.00% inhibitor concentration and 88.33% at 2.50% inhibitor concentration respectively. This shows that rosemary performed excellently in both corrosive environments.
