| Summary: | Abstract Methanolic extraction (ME) of terminalia bentzoe leaves and its aqueous (QF) and n-butanol (nBF) fractions are investigated as sustainable green compounds for both anticorrosion and antimicrobial activity. Extracted and fractionated phytochemicals and their functional groups are detected by GC-MS and FTIR. According to the electrochemical results, ME, QF and nBF samples are considered as anodic inhibitors that mainly inhibit the anodic dissolution of copper (Cu) in 0.6 M NaCl solution. Their inhibition efficiencies increase by increasing their concentrations up to 60 ppm, and the highest value of inhibition efficiency is found to be 94.4% for nBF. The presence of the protective adsorbed layer from the extracted and fractionated phytochemical compounds onto the Cu surface was supported by FESEM analyses and theoretical. On the other hand, exploring the antimicrobial activity of ME, QF and nBF samples against Staphylococcus aureus, Bacillus cereus, Listeria monocytogenes, Escherichia coli, Salmonella typhi, Shigella boydii, Aspergillus niger and Candida albicans was made by using modified Kirby-Bauer disc diffusion technique. Data indicated good resistance against a variety of bacterial infections for the studied green compounds. |
