Digallic acid is a polyphenolic compound found in Pistacia lentiscus. [1] Digallic acid is also present in the molecule of tannic acid. [2] Digalloyl esters involve either -meta, or -para depside bonds. [3] Tannase is an enzyme that uses digallate to produce gallic acid. This enzyme can also be used to produce digallic acid from gallotannins. [4]

Digallic acid (gallic acid 5,6-dihydroxyl-3-carboxyphenyl ester), but not gallic acid, is a potent inhibitor of MoLV RTase, resulting in a ∼90% inhibition at the 0.5-μg/ml concentration (15). Digallic acid is partially competitive with respect to the template-primer (A) n · (dT) 12–18 and noncompetitive with respect to dTTP.

Digallic acid is an antioxidant, antimutagenic, antigenotoxic, and anti-hyperuricemic compound. Digallic acid is a reverse transcriptase and XOD, URAT1 (IC 50: 5.34 μM) inhibitor. Digallic acid scavenges DPPH· and O2·− radicals. Digallic acid induces apoptosis. Digallic acid can be isolated from the fruits of Pistascia lentiscus.

Digallic Acid: A natural polyphenolic. CAS Number: 536-08-3. Synonyms: m-Galloylgallic acid, NSC 59263. Purity: ≥95% (mixture of para and meta isomers).

Sol in 1900 parts water at 25°; in 50-60 parts boiling water; sol in methanol, ethanol, acetone; sparingly sol in ether, glacial acetic acid. Upon addn of KCN to an aq soln a transitory pink color appears, which returns on shaking. NOTE: In pharmaceutical literature the name digallic acid is frequently confused with tannic acid.
