Main Applications of Gallic Acid Supplement

Gallic acid is a versatile compound with various applications in different industries. It can be used to synthesize gallic acid esters, which are powerful antioxidants commonly used in food products. These esters can be categorized into lower and higher esters based on the carbon atom count in the alkyl group.

In terms of biological activities, gallic acid exhibits anti-inflammatory, antioxidant, and anti-free radical properties. It also shows anti-tumor effects and can inhibit the metastasis of mast cell tumors. Additionally, it has a protective effect on the liver and can induce vascular endothelium-dependent contraction and relaxation.

In medical applications, gallic acid shows antibacterial and antiviral effects, inhibiting the growth of various bacteria and fungi. It also has potential anti-tumor properties, inhibiting lung adenoma formation in mice. Moreover, it has astringent, hemostatic, and antidiarrheal effects, making it useful in treating diseases like bacillary dysentery.

Apart from its medicinal uses, gallic acid can be utilized in various other industries. It is used in the production of fuels, fireworks stabilizers, inks, and plant growth regulators. It can also be used as a UV absorber, flame retardant, and semiconductor photoresist raw material. Gallic acid finds applications in tanning, as a photographic developer, and as an analytical reagent in the detection of certain compounds.

Gallic Acid Supplement Extraction Method

Currently, the majority of industrially produced plant resources used for extracting and preparing gallic acid come from gallnuts. Gallic tannic acid is a complex mixture that contains gallic acid, as well as gallic acid and glucose combined in the form of glycosides or esters. Tannic acid can be hydrolyzed under pressure to produce gallic acid and glucose. The industrial production process typically involves producing gallic acid esters through acid hydrolysis or fermentation, followed by hydrolyzing digallate into Gallic Acid Supplement using methods such as normal pressure or high pressure hydrolysis.

A method has been developed to extract and separate Gallic Acid Supplement from rhombus shells. This method involves taking a certain quantity of rhombus shells (containing 4% gallic acid), crushing them to a specific degree, and decocting them three times with water for one hour each time. The extracts are then combined and concentrated to half the volume. After removing the precipitate, the solution is further concentrated to a smaller volume and extracted with ethyl acetate. The ethyl acetate extract is combined, recovered, and concentrated to one-third of the volume. After removing the precipitate, the solution is extracted with water using ethyl acetate, and the water extracts are combined, concentrated, and decolorized with 1% activated carbon. The decolorized aqueous solution is then extracted with ethyl acetate in batches, and the ethyl acetate extracts are combined, concentrated, and subjected to crystallization to obtain crude gallic acid with a content exceeding 85%. The crude gallic acid can be reconstituted with water and organic solvents based on specific requirements.

This process is straightforward, environmentally friendly, and boasts a high yield, making it a green and efficient method for extracting Gallic Acid Supplement.
