Tannic Acid Introduction
Tannic acid is a specific form of tannin, a type of polyphenol. Its weak acidity (pKa around 6) is due to the numerous phenol groups in the structure. The chemical formula for commercial tannic acid is often given as C76H52O46, which corresponds with decagalloyl glucose, but in fact it is a mixture of polygalloyl glucoses or polygalloyl quinic acid esters with the number of galloyl moieties per molecule ranging from 2 up to 12 depending on the plant source used to extract the tannic acid. Commercial tannic acid is usually extracted from any of the following plant parts: Tara pods (Caesalpinia spinosa), gallnuts from Rhus semialata or Quercus infectoria or Sicilian sumac leaves (Rhus coriaria).
It is a light yellow to tan solid with a faint odor. Sinks and mixes with water.
It is a gallotannin obtained by acylation of the five hydroxy groups of D-glucose by 3,4-dihydroxy-5-[(3,4,5-trihydroxybenzoyl)oxy]benzoic acid (a gallic acid dimer). It has a role as a carcinogenic agent, a metabolite and a geroprotector. It is a gallotannin, a D-glucoside and a monosaccharide derivative. It is functionally related to a gallic acid.
It also is a polyphenolic compound. It is a type of the commercially available tannins. It acts as a weak acid. It is found in the nutgalls formed by insects on twigs of certain oak trees (Quercus infectoria and other Quercus species). It is removed and used as medicine. In the old days it was used as antidote against different poisons. Nowadays, tannic acid is applied topically for the treatment of cold sores, diaper rash, fever blisters and poison ivy. It is also taken by mouth and applied directly for bleeding, chronic diarrhea, dysentery, bloody urine, painful joints, persistent coughs, and cancer.
