| Popis: | The leaves essential oil of Tetraclinis articulata (Vahl) Masters was analyzed by GC and GC-MS, and then tested as corrosion inhibitor of carbon steel in 0.1 N of HCl, H2SO4 and HNO3, using electrochemical polarization method. It was also screened for possible biological activities especially antioxidant, antimicrobial, anti-5-lipooxygenase and anti-xanthine oxidase activities. Thirty-five components were identified, accounting for 96.6% of the total essential oil. The major components were α-pinene (29.0%), bornyl acetate (25.5%), camphor (16.6%) and limonene (6.7%). The corrosion rate of carbon steel decreased in the presence of the essential oil giving increased inhibition efficiency with increasing essential oil concentration. Polarization curves showed that this essential oil behave as mixed-type inhibitor with dominated cathodic character in the studied acidic media. The investigated essential oil showed substantial antimicrobial activity, which S. aureus was found to be the most sensitive b... |
