(1) The gallic acid ester compound can be synthesized by using gallic acid as a raw material, and the alkyl ester of gallic acid can be classified into a lower ester (such as a methyl ester, an ethyl ester, a propyl ester, etc And a higher ester according to the number of alkyl carbon atoms (such as octyl ester, lauryl ester, octadecyl alcohol ester, etc.), these ester compounds are excellent food antioxidants;
(2) Gallic acid has various biological activities such as anti-inflammatory, anti-bacterial, anti-viral, anti-mutation, anti-oxidation and anti-free radical; in vitro against Staphylococcus aureus, sarococcus, alpha-typeococcus, Neisseria, Pseudomonas aeruginosa, Shigella flexneri, H. typhimurium Hd, Paratyphoid bacillus A and the like have an inhibitory effect, and the inhibitory concentration is 5 mg/ml. In vitro, it has a bacteriostatic effect on 17 kinds of fungi at a concentration of 3 %, and has a certain inhibitory effect on influenza virus. It can treat dysentery. It has astringent, hemostasis and antidiarrheal effects.
Gallic acid also has an anti-tumor effect, can inhibit the metastasis of mast cell tumor, whereby prolonging the survival period; it is also a later suitable candidate for trypanosome killing; it has a protective effect on the liver and can resist liver physiology and Vascular endothelium-dependent contraction and endothelium-dependent relaxation can be induced by inhibiting endothelial NO production. It must be pointed out that pharmaceutical and food gallic acid cannot use industrial gallic acid, and pharmaceutical grade and food grade Gallic acid must be used;
(3) Other applications: Gallic acid can be used to make a variety of fuels, fire-fighting stabilizers, blue-black inks (galonic acid and trivalent iron ions to form blue-black precipitates, which are the raw materials for blue-black Ink) and flute agents, which can be used as plant growth regulator, combined with vitamin C as an enhanced bait fish, UV absorber, flame retardant, semiconductor photoresist material, can be formulated with anti-rust primer and aluminum alloy organic coating, used To prepare water-based drilling mud Fluidizer, the effect is comparable to or better than lignosulfonate. It is also used in the industry for tanning; it can also be used as a photographic developer. It is also used as a developer and an analytical reagent For detecting free inorganic acids, dihydroxyacetone, alkaloids, metals, and the like.
