Physical properties
| Property | Value |
|---|---|
| Measured boiling point | 123 °C at 11 mmHg (1.47 kPa) [^1] |
| Reference pressure | 1.47 kPa (reduced pressure) |
| Atmospheric-pressure value | ≈274 °C at 760 mmHg (Sigma-Aldrich catalog value; literature range 268–274 °C) [^1] |
| Data source | PubChem CID 9855795 (123 °C @ 11 mm Hg); Sigma-Aldrich (274 °C, lit.); NIST WebBook lists no phase-change data for CAS 4630-07-3 [^1] |
Thermal-extraction context
Valencene is a low-volatility sesquiterpene; atmospheric boiling has not been independently confirmed by NIST, and evaporation from botanical matrix occurs at far lower temperatures via vapor-pressure-driven loss.
Reported biological activity
Human evidence
No verified controlled human study of inhaled isolated valencene was identified for this archive [^2].
Animal or laboratory evidence
In vitro and animal studies report anti-allergic mast-cell effects, anti-inflammatory cytokine suppression (mouse, intraperitoneal), and antimicrobial activity at high concentrations; a skin-protection study is topical, not inhalation 1.
Traditional or anecdotal claims
Citrus aromatics used traditionally in perfumery and flavouring.
Cannabis laboratory results
Trace in Italian hemp cultivars (≤0.4 g/100 g of hydrodistilled essential oil) 2; no batch-level peer-reviewed quantitative data were located for drug-type flower. Consult Lab Results for batch-level measurements.
