A master’s thesis at the College of Science at the University of Basra discussed a biophysical study of some active compounds extracted from the laurel plant. The thesis of the researcher (Esraa Abdullah) included the isolation of flavonoid and alkaloid compounds from the leaves of the laurel plant and the study of their effectiveness as inhibitors of iron alloy corrosion in the environment of RO water and HCl acid, in addition to preparing a chemical inhibitor. It also studied the effect of the optimal concentration of inhibitors in the environment of RO water on blood parameters, liver and kidney functions in laboratory animals, in addition to their effect on two types of Gram-negative and Gram-positive bacteria and measuring their effectiveness as antioxidants. The study concluded that the flavonoid extract had the highest inhibition efficiency and did not show an effect on the effectiveness of liver enzymes and kidney function in addition to its effect in inhibiting bacterial growth and antioxidant. The study recommended the use of plant extracts as corrosion inhibitors.
