Tannic acid is a pale yellow amorphous powder or a glossy scale-like or spongy solid. No special odor, bitter

and astringent, astringent. Exposure to air and sunlight gradually darkens. Soluble in cold water, can be

dissolved in water without limit; soluble in methanol, ethanol, acetone and ethyl acetate, insoluble in benzene,

ether, chloroform, petroleum ether and carbon disulfide. The tannic acid aqueous solution is weakly acidic,

easily oxidized, oxidizes faster in alkaline solutions, and the solution is darker in color. Case of ferric ions,

the solution was blue and black, and precipitation with white gelatin, alkaloids. With lead, aluminum, zinc,

barium and other metal ions to generate multi-nuclear complexes, with special colors of insoluble salts.

When tannic acid is heated to 210 to 215°C, it is decomposed into pyrogallic acid and CO2.

1. Convergence:

Since the chinese gall extract contained therein precipitates five times as much of the protein as the protein

(Figure 7), the skin, mucous membranes, and ulcers are exposed to tannic acid, and the tissue protein is solidified,

causing a layer of capsules to converge and the small blood vessels to be compressed. Contraction, blood coagulation

play hemostatic effect; glandular cell protein is caused by coagulation and secretion inhibition, resulting in mucous

membrane dry, nerve endings protein precipitation, can be a weak local anesthetic phenomenon. Citric acid can form

insoluble compounds with several metals, alkaloids, or oximes, and is therefore used as an antidote. Citric acid has

no effect on the normal small intestine movement, and it can reduce intestinal inflammation due to its astringent effect,

so it can prevent diarrhea. If there are stimuli such as bacteria and poisons in the gastrointestinal tract, tannic acid

preparations should not be used. How much tannic acid can interfere with the absorption of food (precipitate protein),

but in the alkaline environment of the small intestine, the protein can be re-released, so a small amount of tannic acid

in food or drink is harmless, but when a large number of excessive drinking Can delay the absorption of food. A greater

amount can even cause irritation, corrosion, especially when fasting can cause pain, vomiting, diarrhea, or constipation.

2. Antibacterial effect:
chinese gall extract still contains other antibacterial active ingredients, mainly distributed in the skin, the decoction of

Gallnut has no antibacterial effect. Gallnut extract has inhibitory effects on Pseudomonas aeruginosa, Shigella, Proteus,

Escherichia coli, Salmonella typhi, Enterobacteriaceae, Bacillus anthracis, Diphtheria bacilli, Staphylococcus aureus,

Streptococcus pyogenes, and pneumococcus. Not because of the acidity of tannic acid, but because of its coagulation

effect on the protein; the gallnut solution after the extraction of enamel by ethyl ether still has antibacterial effect.

3. Detoxification:
chinese gall extract can form insoluble complexes with many heavy metal ions, alkaloids and hydrazines, so it can

be used as a chemical antidote.

4. Others:
chinese gall extract is difficult to absorb in the gastrointestinal tract. When it passes through the gastrointestinal

tract, it is hydrolyzed into gallic acid. Gallic acid has no astringent effect and is easily absorbed and decomposed

in the body. If tannic acid is absorbed excessively on the surface of mucous membranes and wounds, it can lead

to necrosis of the center of the lobule of the liver. Gallic acid and its esters can inhibit the contractile effect of

bradykinin on the guinea pig ileum.
