Gallic acid Main application
1. Antioxidants
Gallic acid can be used as raw material to synthesize gallate esters. The alkyl esters of gallic acid can be divided into low esters (such as methyl ester, ethyl ester, propyl ester, etc.) and high esters (such as octyl ester, lauryl ester, octadecyl alcohol ester, etc.) according to the number of alkyl carbon atoms. These ester compounds are excellent food antioxidants.
2. Biological activity
Gallic acid has many biological activities such as anti-inflammatory, anti-mutation, anti-oxidation and anti-free radical. At the same time, gallic acid has anti-tumor effect, which can inhibit the metastasis of mast cell tumor and prolong the survival time. It is also a relatively suitable candidate drug to kill trypanosoma; It has a protective effect on liver and can resist the physiological and biochemical changes of liver induced by carbon tetrachloride. Endothelium-dependent contraction and endothelium-dependent relaxation can be induced by inhibiting the production of endothelial NO
3. Pharmaceutical applications
① Anti-bacterial and anti-viral: In vitro to Staphylococcus aureus, Sarcina, α-type kedococcus, Neisseria, Pseudomonas aeruginosa, Fredriniella dysenteriae, typhoid Hd, paratyphoid A and other inhibitory effects, the inhibitory concentration of 5mg/mL. In vitro, it has antibacterial effect on 17 kinds of fungi at 3% concentration, and also has certain inhibitory effect on influenza virus. It can cure dysentery. It has the effect of astringent, hemostasis and diarrhea.
② Anti-tumor: It has strong inhibitory effect on lung adenoma caused by morpholine and sodium nitrite.
4. Other applications
Gallic acid can be used to make a variety of fuels, firework stabilizers, blue-black inks (gallic acid and ferric ion produce blue-black precipitates, which is the raw material of blue-black ink) and flute agents, can be used as plant growth regulators, combined with vitamin C as a strengthening food for fish, but also UV absorbent, flame retardant, semiconductor photoresist raw material, It can prepare anti-rust primer and organic coating of aluminum alloy, prepare fluidizing agent for water-based drilling mud, and its effect can be comparable to or even better than lignosulfonate. Also used in industry for leather; It can also be used as photographic developer. It is also used as a developer and an analytical reagent for the detection of free inorganic acids, dihydroxyacetone, alkaloids and metals.
