Function

What is Gallic Acid?

Gallic acid is commonly used in the pharmaceutical industry. It is used as a standard for determining the phnol content of various analytes by the Folin - Ciocalteau assay; results are reported in gallic acid equivalents. Gallic acid can also be used as a starting material in the synthesis of the psychedelic alkaloid mcaline.

Gallic acid seems to have anti-fungal and anti - viral properties. Gallic acid acts as an antioxidant and helps to protect human cells against oxidative damage. Gallic acid was found to show cytotoxicity against cancer cells, without harming healthy cells. Gallic acid is used as a remote astringent in cases of internal haemorrhage. Gallic acid is also used to treat albuminuria and diabetes. Some ointments to treat psoriasis and external haemorrhoids contain gallic acid.

Gallic acid is an organic acid found in foods such as blueberries, apples, flaxseeds, tea leaves, oak bark, walnuts and watercress. Its supplements are available as capsules, ointments and liquid extracts, and have been used traditionally to treat a variety of ailments. The form and dosage depend on the age of the patient and condition being treated. Gallic acid supplements are generally safe to use.

Gallic acid (also known as 3,4,5-trihydroxybenzoic acid) is a trihydroxybenzoic acid, a type of enolic acid, found in gallnuts, sumac, witch hazel, tea leaves, oak bark, and other plants. The chemical formula of gallic acid is C6H2(OH)3COOH. It is found both free and as part of hydrolyzable tannins. The gallic acid groups are usually bonded to form dimers such as ellagic acid. Hydrolyzable tannins break down on hydrolysis to give gallic acid and glucose or ellagic acid and glucose, known as gallotannins and ellagitannins, respectively.

Gallic acid is an important component of iron gall ink, the standard European writing and drawing ink from the 12 th to 19th century with a history extending to the Roman empire and the Dead Sea Scrolls. Pliny the Elder (23-79 AD) describes his experiments with it and writes that it was used to produce dyes. Galls (also known as oak apples) from oak trees were crushed and mixed with water, producing tannic acid (a macromolecular complex containing gallic acid). It could then be mixed with green vitriol (ferrous sulfate) - obtained by allowing sulfate - saturated water from a spring or mine drainage to evaporate - and gum arabic from acacia trees; this combination of ingredients produced the ink. 

Gallic acid was one of the substances used by Angelo Mai (1782-1854), among other early investigators of palimpsests, to clear the top layer of text off and reveal hidden manuscripts underneath. Mai was the first to employ it, but did so "with a heavy hand", often rendering manuscripts too damaged for subsequent study by other researchers.Early photographers, including Joseph Bancroft Reade (1801- 1870) and William Fox Talbot (1800 - 1877), used gallic acid for developing latent images in calotypes. It has also been used as a coating agent in zincography.
