Scopoletin
chemical compound
Scopoletin is a coumarin found in the root of plants in the genus Scopolia such as Scopolia carniolica and Scopolia japonica, in chicory, in Artemisia scoparia, in the roots and leaves of stinging nettle (Urtica dioica), in the passion flower, in Brunfelsia, in Viburnum prunifolium, in Solanum nigrum, in Datura metel, in Mallotus resinosus, and in Kleinhovia hospita. It can also be found in fenugreek, vinegar, some whiskies and in dandelion coffee. A similar coumarin is scoparone. Scopoletin is highly fluorescent when dissolved in DMSO or water and is regularly used as a fluorimetric assay for the detection of hydrogen peroxide in conjunction with horseradish peroxidase. When oxidized, its fluorescence is strongly suppressed.
Chemistry
Biosynthesis
Like most phenylpropanoids, the biosynthetic precursor to scopoletin acid is 4-coumaroyl-CoA. Scopoletin is derived from 1,2-benzopyrones which is the core structure of coumarins formed through hydroxylation of cinnamates, trans/cis isomerization of the side chain, and lactonization. And CYP98A (C3’H) are enzymes belonging to the cytochrome P450 family that catalyze the meta-hydroxylation of p-coumarate derivatives, an important step in the phenylpropanoid pathway. For scopoletin, most of biosynthetic investigations are based on Arabidopsis thaliana.
Derivatives/Related Compounds
Scopolin is a glucoside of scopoletin formed by the action of the enzyme scopoletin glucosyltransferase.
The enzyme has been characterised from tobacco and Duboisia myoporoides.
Begin with the source’s own compact description: “Scopoletin” is chemical compound. The dossier treats that line as a proposition to test through Scopoletin, chemical and compound, not as a finished interpretation.
Why this record matters
The phrase “chemical compound” 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.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Jul 19, 2026. The linked authority identifier is Q2472366. None of the 0 selected statements returned an explicit reference.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. 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.
