Application of Medicinal Tannic Acid Tannic Acid Raw Materials

Tannic acid (tannic acid) is a multifunctional natural polyphenolic compound widely found in plants such as grapes, galls, tea, Bauhinia, cocoa, etc‌Its chemical formula isC76H52O46The relative molecular weight is between500to3000Between Dalton‌

Tannic acid usually appears as a yellow or brown amorphous powder, with some scales and a subtle special odor. The taste is extremely bitter and astringent. Its melting point is218Celsius, soluble in water and ethanol, also soluble in acetone, but not in chloroform or ethyl acetate‌

chemical properties

Tannic acid, as a weak acid, contains multiple phenolic hydroxyl groups, thus exhibiting significant biological and pharmacological activities. It can exhibit diverse chemical properties and functions through complexation reactions and chelation with biomolecules such as proteins and metal ions‌
