Phytochemical Analysis and Antioxidant Properties of Syzygium cumini Fruit as a Corrosion Inhibitor

Abstract:

Syzygium cumini is a plant belonging to the Myrtaceae family and is widely used in medicine and food. However, its application in the engineering field is still very minimal, particularly as an anti-corrosion material. There are also limited studies on the quantitative screening of phytochemical and bioactivity of S. cumini. Therefore, this study aims to analyze the chemical compounds of S. cumini fruit as a corrosion inhibitor as well as determine total tannin (TTC) and flavonoid (TFC) content. The extraction process was carried out with a soxhlet extractor using 96% ethanol solvent. Characterization was then conducted using FTIR (Fourier Transfer Infrared) test and total antioxidant test with a UV-Vis spectrophotometer. Spectrum analysis showed the presence of Hydroxyl (O-H), Alkane (C-H), Carbonyl (C=O), Aromatic Ether (C-O), and Amine (C-N) functional groups. The results also revealed that TTC was 26.83% higher, while TFC was 2.11%. In addition, S. cumini fruit was reported to contain high functional groups and antioxidant compounds, which were useful as active molecular inhibitor ingredients.
