Source-derived summary

Digallic acid is a polyphenolic compound found in Pistacia lentiscus. Digallic acid is also present in the molecule of tannic acid. Digalloyl esters involve either -meta, or -para depside bonds.

Tannase is an enzyme that uses digallate to produce gallic acid. This enzyme can also be used to produce digallic acid from gallotannins.

Editorial summary

This brief starts where responsible research should: with the source description of “Digallic acid” as chemical compound. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewUseful for establishing the present vocabulary of the subject while preserving a route back to the evidence on which that vocabulary rests. The current 53-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. The account is most persuasive where Digallic, acid and chemical can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the science & nature register because the source frames it as chemical compound. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Feb 25, 2026. The linked authority identifier is Q4140499. None of the 0 selected statements returned an explicit reference.

Critical limits

Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
