Gallic acid is a trihydroxybenzoic acid found in gallnuts, sumac, witch hazel, tea leaves, oak bark, and other plants.Gallic acid is found both free and as part of hydrolyzable tannins. The gallic acid groups are usually bonded to form dimers such as ellagic acid. Hydrolysable tannins break down on hydrolysis to give gallic acid and glucose or ellagic acid and glucose, known as gallotannins and ellagitannins respectively.
Function
Gallic acid has anti - inflammatory, anti - mutation, anti - oxidation, anti - free radical and other biological activities.
Antibacterial and antiviral: it has inhibitory effect on Staphylococcus aureus, Octadiae, α -keptococcus, Neisseria, Pseudomonas aeruginosa, Dysentery froudrelli, Typhoid bacillus Hd, paratyphoid bacillus A and so on in vitro, and its inhibitory concentration is 5mg/mL. In vitro, it had inhibitory effect on 17 kinds of fungi at 3% concentration, and also had some inhibitory effect on influenza virus. Can treat bacterial dysentery. It has the functions of convergence, hemostasis and diarrhea. Gallic acid can be used to manufacture a variety of fuel, fireworks stabilizer, blue-black ink (gallic acid and ferric iron ion precipitation, blue-black is blue-black ink raw material) and its agent, can be used as plant growth regulator, cooperate with vitamin C as a bait fish farming, and uv absorber, flame retardants, semiconductor photo imageable etching resist the raw material, Antirust primers and aluminum alloy organic coatings can be prepared, and fluidizing agents for water-based drilling mud can be as good as or better than lignosulfonate.
It is also used in industry for tanning; Can also do photographic developer. Also used as a developer and detection of free inorganic acid, dihydroxyacetone, alkaloid and metal analysis reagent.
Application
1.Applied in food filed,gallic acid can be produced into wine, canned, condensed juice and other more nourishment;
2. .Applied in cosmetic industry,gallic acid used as active ingredients of skin care products;
3. Widely applied in pharmaceutical grade.
4. Applied in dyes, chemicals and organic synthesis, as well as in the analysis of rare metals.
