What Is Galla Chinensis ?

Galla Chinensis is an important member of the traditional Chinese medicine family. It is the gall on the leaves of Rhus chinensis Mill, Rhus potaninii Maxim, or Rhus punjabensis Stew, which is mainly formed by the parasitization of the gall aphid Melaphis chinensis (Bell). At present, the pharmacological research mainly focuses on antibacterial research.

The main component of Galla Extract is Tannic acid, which is the main raw material for the production of gallic acid. Our Galla Chinensis has a large output and is widely distributed, which is convenient for large-scale development and production.

2) Effect on the liver

Studies have shown that it has anti-HBV efficacy.

3) Anti-inflammatory and antibacterial effects

It has a strong inhibitory effect on Escherichia coli, Staphylococcus aureus, Pasteurella, and Streptococcus, and the antibacterial effect is significantly better than that of berberine.

4) Prevention and treatment of AIDS

Gallotannin are esters of gallic acid and polyols,that is one of the main varieties of tannins used in anti-HIV research.

5) Trypanicidal effect

It has potent insecticidal effects on both bloodstream and procirculation trypanosomes.

Main applications of gallic acid

1. Antioxidants

Gallic acid ester compounds can be synthesized using gallic acid as raw material. 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) according to the number of carbon atoms in the alkyl group. , lauryl ester, octadecyl alcohol ester, etc.), these ester compounds are food antioxidants with excellent performance. In the 1980s, Japan already used antioxidant G1000, EG-5 emulsion and EG-5 oil composed of 95% gallic acid and other additives, especially propyl gallate as an antioxidant, which can be used in edible fats and oils. Prevents rancidity and deterioration. Propyl gallate (PG) has been approved for use in many countries and is produced in Japan, the United States, Germany, and the United Kingdom. Most processed aquatic products abroad use gallic acid as an antioxidant by dipping or spraying.

2. Biological activity

Gallic acid has various biological activities such as anti-inflammation, anti-mutation, antioxidant, and anti-free radicals. At the same time, gallic acid has anti-tumor effects and can inhibit the metastasis of mast cell tumors, thus prolonging survival. It is also a relatively suitable trypanosomaticide. Candidate drug; has a protective effect on the liver and can resist the physiological and biochemical changes of the liver induced by carbon tetrachloride; can induce vascular endothelium-dependent contraction and endothelium-dependent relaxation by inhibiting the production of endothelial NO.

3. Medical applications

1. Antibacterial and antiviral: In vitro, it has inhibitory effects on Staphylococcus aureus, Sarcina, α-type Keyococcus, Neisseria, Pseudomonas aeruginosa, Shigella freundii, Typhimurium HD, Paratyphi A, etc. Its inhibitory concentration is 5mg/mL. In vitro, it has an antibacterial effect on 17 types of fungi at a concentration of 3%, and also has a certain inhibitory effect on influenza viruses. Can treat bacillary dysentery. It has astringent, hemostatic and antidiarrheal effects.

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

4. Other applications

Gallic acid can be used to make a variety of fuels, fireworks stabilizers, blue-black ink (gallic acid and ferric ions generate a blue-black precipitate, which is the raw material of blue-black ink) and flute agents, and can be used as a plant growth regulator, and Vitamin C is used as a strengthened bait for fish farming. It is also a UV absorber, flame retardant, and semiconductor photoresist raw material. It can be used to prepare anti-rust primers and aluminum alloy organic coatings, and to prepare fluidizers for water-based drilling mud. Its effect is Comparable to, or even better than, lignosulfonates. It is also used industrially for tanning; it can also be used as a photographic developer. It is also used as a developer and analytical reagent for the detection of free inorganic acids, dihydroxyacetone, alkaloids and metals.
