Propelargonidin
group of chemical compounds
Propelargonidins are a type of condensed tannins formed from epiafzelechin. They yield pelargonidin when depolymerized under oxidative conditions.
Propelargonidins can be found in the rhizomes of the fern Drynaria fortunei, in buckwheat (Fagopyrum esculentum), and in the edible halophyte Carpobrotus edulis.
Examples
Geranins A and B, dimers found in Geranium niveum
Selligueain A, a trimer found in the rhizome of Selliguea feei
the trimeric propelargonidin epiafzelechin-(4β→8)-epiafzelechin-(4β→8)-4′-O-methyl-(−)-epigallocatechin can be isolated from the stem bark of Heisteria pallida.
Begin with the source’s own compact description: “Propelargonidin” is group of chemical compounds. The dossier treats that line as a proposition to test through Propelargonidin, group and chemical, not as a finished interpretation.
Why this record matters
The phrase “group of chemical compounds” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
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 Jun 26, 2023. The linked authority identifier is Q7250137. None of the 0 selected statements returned an explicit reference.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. 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.
