2,4-Patchouladiene is a trace sesquiterpene hydrocarbon most useful in AromaForge as a composition and chemotaxonomic marker rather than a well-studied isolated bioactive. Live sources support its identity, structure, and occurrence in Cyperus and other essential-oil profiles, including the local Bengali nagarmotha record. Direct mechanism, human-use, and constituent-specific safety literature appear sparse in this research pass, so archive copy should present 2,4-patchouladiene as a niche patchouli-skeleton aroma constituent with clear evidence gaps rather than inferred wellness activity.
Chemical identity and composition
PubChem resolves 2,4-patchouladiene to CID 74819450 with formula C15H22 and InChIKey DPHLFUXQEZYZAP-UHFFFAOYSA-N. The local Bengali nagarmotha profile lists it at 1.04%, consistent with literature that places it among minor sesquiterpenes in Cyperus-related oils. The hydrogen count indicates a relatively unsaturated sesquiterpene hydrocarbon compared with more common C15H24 sesquiterpenes.
Aroma and practical use
- Use the recorded woody, earthy, patchouli-like 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 1997 Phytochemistry paper on Cyperus alopecuroides reported 2,4-patchouladiene among the sesquiterpenes identified in hydrodistillation products by spectroscopic methods and chemical conversions.
This is the most direct source located for the compound as an individually identified natural-product constituent.
This reference does not establish a therapeutic result or a safe use level for a custom oil blend.
A 2021 Frontiers formula-composition paper listed 2,4-patchouladiene at 1.01% in a volatile-oil profile, showing that the compound continues to appear in modern GC-MS essential-oil datasets as a minor component rather than a dominant active.
This supports current analytical relevance without implying constituent-specific efficacy.

A recorded constituent reference, not a recommended oil dilution. Product category, source applicability and all contributing oils must be checked before use.
unverified reference · No source provenance attachedNo constituent-specific RIFM, IFRA, EFSA, or clinical safety review for isolated 2,4-patchouladiene was verified in this pass.

Because the located literature is mainly compositional, safety assumptions should not be extrapolated from other patchouli-related sesquiterpenes.

Constituents it may interact with
No constituent-pair interaction is recorded for this identity. The report does not assume either amplification or incompatibility.
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 isolated human or animal pharmacology study specific to 2,4-patchouladiene was verified in this pass.
- Constituent-specific odor descriptions from primary fragrance references were sparse, so the aroma descriptors here are conservative and structure-informed.
- A standalone constituent-specific safety assessment was not located.
- The numeric dermal reference lacks source provenance; a verified flag alone is insufficient.
- Some findings do not record an explicit exposure route; consult the linked study before applying them to a use.
