Description

General description

Tannic acid (TA) is a natural, non-toxic organic acid with corrosion inhibitive property for metals and alloys. A chemiluminescence (CL) system of KIO₄ (potassium periodate)–H₂O₂ (hydrogen peroxide)–Tween40 has been employed in the detection of tannic acid in industrial wastewater. Tannic acid hydrolyzes to form mainly glucose and gallic acid. Its astringent property is due to the presence of polyphenolic groups.

Application

Tannic acid may be used in the following processes:

Synthesis of ferric tannate complexes by reacting with metallic iron.
As a protein deproteinizing agent in genomic and plasmid DNAs preparation.
As a reductant in the synthesis of metal nano particles.

Multiple studies have been recorded on the synthesis and design of multi-aim anti-Alzheimer molecules. Using dual butyrylcholinesterase/acetylcholinesterase inhibitor molecules has attracted more interest in the therapy for Alzheimer's disease. In this study, a tannic acid compound showed excellent inhibitory effects
