Antifungal Activity and Anti-Corrosion Inhibition of Origanum Compactum Extracts

, an endemic medicinal plant of the Moroccan North, were extracted with the soxhlet apparatus using the following solvents: petroleum ether, hexane, chloroform and methanol. The results showed that aqueous and methanol 80 % extracts were very effective to control the growth of the fungus with 100% of the inhibition percentage at the concentration of 25g/l. Moreover, the percentage of the inhibition of the mycelial growth was more than 97% at 1,125 g/l for the aqueous extract. From the soxhlet extracts, petroleum ether extract presented an important antifungal activity (83%) followed by methanol extract (45,9%). While hexane and chloroform extracts were less effective. For the corrosion application, the results showed variation in inhibition performance of the inhibitor with varying concentration. The results obtained with different methods are in good agreement. Langmuir model was tested to describe the adsorption behaviour of inhibitor on the carbon steel surface.
