Junenol is a sesquiterpene alcohol found in several essential oils and propolis-type natural products, but the current evidence base is uneven. Publicly accessible data are strongest for identity, biosynthetic context, and occurrence as a marker constituent in some oils, including palo santo and Acritopappus confertus. Bioactivity signals exist, but they are usually reported for complex oils or mixtures rather than for purified junenol. For AromaForge, junenol is best framed as a chemistry and profiling constituent with early preclinical associations, not as a validated standalone active.
Chemical identity and composition
PubChem maps junenol to CID 6452077 with formula C15H26O and a sesquiterpene-alcohol eudesmane skeleton. Public synonym records link junenol to the older descriptor eudesm-4(14)-en-6alpha-ol and CAS 472-07-1. Within the archive it appears in palo santo essential oil at 1.55%, while recent botanical papers also describe (+)-junenol as a major or marker constituent in Acritopappus confertus and as an identified though minor constituent in other essential oils.
Aroma and practical use
- Use the recorded woody, dry, terpenic, resinous, resin descriptors to explore a blend's scent character; perceived strength also depends on the other ingredients.
- Read the route, preparation and experimental context before using a study finding to choose an oil.
Reported benefits and effects
Findings retain their study context. An animal or laboratory result describes that experiment.
A 2025 GC-MS and antimicrobial paper reported (+)-junenol as the main compound in all Acritopappus confertus specimens at 13-52% and proposed it as a chemical marker of that plant material from Chapada Diamantina.

A 2024 Journal of Agricultural and Food Chemistry abstract linked junenol and caryophyllene oxide with phytotoxic effects observed in Copaifera oils and noted that isolated compounds behaved differently from the whole oils, implying synergy or interaction effects.

A 2016 plant biochemistry paper reported the cloning and functional analysis of a 10-epi-junenol synthase from Inula hupehensis, adding direct biosynthetic evidence for a junenol-related sesquiterpene pathway.

Because bioactivity signals are mostly indirect, archive copy should avoid antimicrobial, herbicidal, or metabolic claims for isolated junenol.

Constituents it may interact with
No constituent-pair interaction is recorded for this identity. The report does not assume either amplification or incompatibility.
How the effects were investigated
sesquiterpene biosynthesis from fpp
A plant biochemistry study reported a 10-epi-junenol synthase that converts farnesyl diphosphate into a junenol-related sesquiterpene product, clarifying junenol's biosynthetic pathway context.

No direct public citation is attached to this entry.
phytotoxic association signal
A 2024 phytotoxicity paper associated junenol with observed seed-germination inhibition in Copaifera oils, but the abstract explicitly notes differing activity after compound isolation and suggests mixture interactions matter.

What this report cannot establish
- A reported constituent percentage does not establish an effective human therapeutic dose or the amount absorbed into the body.
- The presence of a constituent does not guarantee a clinical benefit, rash treatment or sleep improvement from a custom blend.
- An unflagged concern or missing use limit does not establish safety for ingestion, inhalation, skin exposure or a particular person.
- A candidate constituent interaction does not establish that two oils amplify one another at the selected proportions.
- Constituent descriptors alone do not establish a precise top, heart or base lifetime in a finished blend.
Known data gaps (5)
- No human clinical studies specific to isolated junenol were verified in this pass.
- Most accessible bioactivity evidence is indirect, mixture-based, or biosynthetic rather than direct pharmacology on purified junenol.
- A transparent constituent-specific dermal or inhalation safety threshold for isolated junenol was not located in the reviewed public sources.
- No constituent-specific numeric dermal reference is available here.
- Some findings do not record an explicit exposure route; consult the linked study before applying them to a use.
