Product Description

Product Profile
Galla gallnut extract is a product extracted from gallnut gallnut as raw material. It mainly contains gallic acid tannins, gallic acid, etc. Ingredients such as tannins and gallic acid have a structure with more ortho-position phenolic hydroxyl groups. By acting as a hydrogen donor, they release hydrogen and combine with free radicals in the environment to terminate the chain reaction caused by free radicals, thus preventing the continuation and progression of the oxidation process. , so it has a strong free radical scavenging effect in the organism, thus producing anti-aging effects. At the same time, because free radicals are scavenged, it protects biological macromolecules caused by free radicals, maintains the flow of cell membranes and the conformation of proteins, and prevents DNA breakage induced by radiation, thereby inhibiting lipid peroxidation, cardiovascular disease, and anti-oxidation. Unique effects in mutation, anti-cancer, anti-cataract, etc.

Pharmacological effects
1. Convergence effect
Gallic tannins can combine with proteins to form water-insoluble macromolecular precipitates. When skin, mucous membranes, and ulcers come into contact with tannins, their tissue proteins are coagulated, forming a layer of film with a convergent effect. At the same time, small blood vessels are also compressed and contracted. Blood coagulates and has hemostatic effect. The protein of glandular cells is coagulated, causing secretion inhibition, drying of mucous membranes, and precipitation of protein in nerve terminals, which may cause weak local anesthesia.

2. Antibacterial effect
Galla chinensis extract is effective against Gram-negative bacteria such as Pseudomonas aeruginosa, Shigella dysenteriae, Proteus, Escherichia coli, Aerobacillus aerogenes, Typhoid bacillus, Staphylococcus aureus, Staphylococcus albus, Group B Streptococcus, Diphtheria pneumonia, and Diphtheria bacilli. , Bacillus anthracis and other Gram-positive bacteria all have varying degrees of inhibitory effects. It also has a strong inhibitory effect on certain pathogenic fungi. It has an inhibitory effect on influenza A PR8 strain virus inoculated in chicken embryos. Its antibacterial mechanism is related to the coagulation effect of the tannins on the protein. In addition, it is also related to other ingredients. The gallnut liquid after removing the tannins still has antibacterial effects.

3. Anti-fertility effect
100% gallic acid glycerin solution has a good spermicidal effect, so this product has a certain anti-fertility effect.

4. Hepatoprotective and antioxidant effects
Gallic tannic acid can prevent the nitration of aminopyrine in the stomach and has significant antioxidant effects. It may inhibit the carcinogenic process of nitrite amines. Intragastric administration of gallic acid tannic acid has a protective effect on acute liver injury caused by CCl4.

5. Anti-ulcer effect
The compound gallnut liquid mainly containing gallnut extract can significantly reduce the amount of bleeding, shorten the bleeding time, and significantly reduce the secretion of gastric juice and gastric acid for gastric mucosal bleeding.

6. Inhibitory effect on smooth muscle
Gallic acid and esters can inhibit the astringent effect of bradykinin on the ileum of guinea pigs.

7. Detoxification
Gallic tannins can form insoluble complexes with many heavy metal ions, alkaloids and glycosides, which have detoxifying effects, so they can be used as chemical detoxifiers. The hydrolyzable tannins in gallnuts also have the effect of reducing the urinary toxin content in the blood of patients with renal failure.

8. Anti-cancer pharmacology
Galla chinensis extract has a high inhibitory rate against mouse sarcoma S180. The hot water extract of Galla chinensis has an inhibitory rate of more than 90% on human cervical cancer JTC-26 in in vitro experiments. Galla chinensis extract also has an inhibitory effect on HeLa cancer cells. The gallic acid contained in gallnut extract has a strong inhibitory effect on morpholine plus sodium nitrite-induced lung adenoma in mice.
