Certificate of Analysis

Classification and structure

Tannins are mainly divided into two categories according to their structure and activity: condensed tannins and hydrolyzed tannins.

Condensed tannins: also known as proanthocyanidins, mainly found in the stems, leaves and fruits of plants such as sorghum, grapes, red bean grass and lotus roots. Its molecular weight is 1000~20000Da, and most of it is a polymer composed of flavonoids-3-ols.
Hydrolyzed tannins: mainly found in the bark and fruits of plants such as chestnuts, raspberries, gallnuts, cotinus coggygria, and witch hazel trees. It is mainly formed by the combination of polyols (such as D-glucose) and gallic acid or hexahydroxydibenzoic acid. Its molecular weight is 500~3000Da, and it is easily degraded by acids, alkalis and some esterases in the intestines.

Main effects

Antibacterial effect: Tannic acid has certain antibacterial activity and can inhibit the growth of certain bacteria and fungi.
Anti-inflammatory effect: Some studies have shown that tannic acid has anti-inflammatory effects, which may be related to its antioxidant properties.
Antioxidant effect: It has antioxidant ability, which can scavenge free radicals and reduce the damage of oxidative stress to cells.
Astringent effect: Because it can bind to proteins to form insoluble complexes, tannic acid can be used as an astringent in medicine to treat minor skin trauma, burns and ulcers.
Hemostatic effect: The astringent properties of tannic acid make it useful for local hemostasis, especially after oral surgery.
Adjuvant therapy: In some cases, It is used as an adjuvant treatment for gastrointestinal discomfort, such as diarrhea.
Application in drug formulations: In drug formulations, It can be used as an excipient to help improve the stability and absorption of drugs.

Application

Tanning and making blue ink: In industry,It is widely used in tanning, which can coagulate soluble proteins in raw hides to make beautiful, clean, flexible and durable leather. At the same time, it is also used to make blue ink.
Food antioxidant: Tannic acid can be used as a food antioxidant to extend the shelf life of food.
Viscosity reducer and filtration reducer for water-based drilling fluid: In oil production, tannic acid can be used as an additive for water-based drilling fluid to reduce the viscosity and filtration loss of drilling fluid.
Skin care products: In skin care products, It can protect against the sun, brighten the skin and improve skin quality.
Clinical medical treatment: It can be used to treat local bleeding, such as toothpaste to protect teeth and prevent gingival bleeding. In addition, it can also be used to clean the colon during colonography.
