Gallic acid, chemical name is 3,4,5-trihydroxybenzoic acid,molecular formula C7H6O5,is a polyphenolic organic compound, widely present in rhubarb,eucalyptus,dogwood and other plants,in food,biological,It is widely used in medicine,chemical industry and other fields.Gallic acid (GA),which is an organic acid,can be found in tea,witch hazel,gall and other plants,also known as gallic acid or gallic acid.Gallic acid ester compounds are excellent food antioxidants.Many studies have pointed out that gallic acid has various biological effects such as anti-free radical,anti-mutation,antibacterial,anti-inflammatory and anti-virus.GA also has anti-tumor effect,which can Inhibits the metastasis of mast cell tumors and prolongs the survival period,it is a natural food compound.It is known from the literature that old tea containing gallic acid (GA) does have health benefits.

Whitening benefits of gallic acid: Gallic acid-zhenyibio

The survey results showed that gallic acid (GA) inhibited melanin synthesis and tyrosinase activity in a significant dose- and time-dependent manner,and decreased the expression of melanin biosynthesis-related protein genes.In addition, GA also inhibits melanogenesis by phosphorylating and activating melanogenesis.GA can inhibit melanin biosynthesis by inhibiting the downstream signaling pathway of melanin biosynthesis.Can be used for the treatment of some skin conditions.

Anticancer effects of gallic acid:

The study found that the cell death caused by gallic acid (GA) acting on Calu-6 and A549 lung cancer cells was related to reactive oxygen species (ROS) and glutathione (GSH).GA inhibited the growth of lung cancer cells.The results showed that 200 or 400umol/L GA could inhibit the growth of vascular endothelial cells and induce cell death after 24h treatment of cells.

Antibacterial, antiviral and antitumor effects of gallic acid:

1. In vitro experiments,it has bacteriostatic effect on 17 kinds of fungi such as Typhoid Bacillus Hd,Staphylococcus aureus, Neisseria,etc.When the concentration is 3%, it can treat bacillary dysentery.It has the functions of astringency,hemostasis,and diarrhea.In addition, studies have shown that it also has a certain inhibitory effect on influenza virus.

2. Studies have shown that GA has an anti-tumor effect and can inhibit the metastasis of mast cell tumors, thereby prolonging the survival period.GA and its ester derivatives have various biological activities such as antioxidant,anti-mutation,and anti-inflammatory.Relevant studies have shown that anti-tumor activity is induced by a combination of different mechanisms.These compounds may become novel agents for the treatment of cancer in the future,which can act alone or in combination with other anticancer drugs to enhance their anticancer effects.

Gallic acid and the treatment of rheumatoid arthritis :

The study found Gallic acid (GA) has pro-apoptotic and anti-inflammatory activities on fibroblast-like synovial cells that cause rheumatoid arthritis.GA can promote the expression of apoptotic proteins in fibroblast-like synoviocytes of rheumatoid arthritis and inhibit the mRNA expression of other inflammatory factors.It is expected to be used for the treatment of rheumatoid arthritis.

The protective effect of gallic acid on liver damage:

Taking mice as the research object,the effect of gallic acid (GA) on carbon tetrachloride-induced liver fibrosis was studied.The results showed that GA could significantly improve the conditions of carbon tetrachloride-induced liver injury and fibrosis in mice in a dose-dependent manner.Therefore,gallic acid (GA) may have a protective effect on liver injury,and theobromine is less likely to cause carbon tetrachloride-induced liver fibrosis in mice,which may be due to its inhibition of hepatic stellate cell activity.

Application of Gallic Acid

Antibacterial and antiviral: In vitro,it has inhibitory effects on Staphylococcus aureus,Sarcines, ¦Á-key coccus, Neisseria, Pseudomonas aeruginosa,Shigella freundii,Typhoid Bacillus Hd,Paratyphoid Bacillus A,etc.The bacterial concentration was 5 mg/ml.In vitro,at a concentration of 3%,it has bacteriostatic effect on 17 kinds of fungi,and also has a certain inhibitory effect on influenza virus.Bacillary dysentery can be treated.Has astringent,hemostasis and antidiarrheal effects.

Anti-tumor: It has a strong inhibitory effect on mouse lung adenoma caused by morpholine and sodium nitrite.

Antioxidants: Gallic acid can be used as raw material to synthesize gallic acid esters.The alkyl esters of gallic acid can be divided into lower esters (such as methyl ester,ethyl ester,propyl ester, etc.) and higher esters ( Such as octyl ester, lauryl ester,octadecyl ester, etc.), these ester compounds are all excellent food antioxidants.

Biological activity: Gallic acid has various biological activities such as anti-inflammatory,anti-mutation,anti-oxidation,and anti-free radicals; at the same time, gallic acid has anti-tumor effect,which can inhibit the metastasis of mast cell tumors,thereby prolonging the survival period; it is also relatively suitable It is a candidate drug for killing trypanosomes; it has a protective effect on the liver and can resist the physiological and biochemical changes of the liver induced by carbon tetrachloride; it can induce vascular endothelium-dependent contraction and endothelium-dependent relaxation by inhibiting the production of endothelial NO.
