Chemistry & Uses
Uses in perfumery :
Valencene is used for aldehydic and citrus notes in small quantities.
Year of discovery :
Data not available.
Natural availability :
Valencene in its natural state can be extracted from Clary Sage Absolute (up to 3%) or Sweet Orange EO.
Isomerism :
Caryophyllene, another sesquiterpene, is an isomer of Valencene. Its smell is less aldehydic and more spicy, close to Black Pepper EO.
Synthesis precursor :
Valencene is a precursor to the synthesis of Nootkatone by oxidation.
Synthesis route :
Valencene is more often synthesized biochemically using enzymes produced by fungi. The enzyme is called valencene synthase and the most used mushroom is the Schizophyllum commune.
Stability :
Terpenes tend to polymerize by oxydation.
Other comments :
Valencene is the only terpene with a powerful aldehydic note.
