δ-Cadinol is an organic compound, a sesquiterpenoid alcohol produced by many plants as well as some animals and microorganisms. It is a white crystalline solid, soluble in isopropyl ether and ethanol. It is also called torreyol, sesquigoyol, pilgerol, cedrelanol, lambertol, and albicaulol.[1][2]
The names may refer to any of two isomers distinguished by the prefixes (+)- and (−)-.[3][4] The (+)-isomer was identified by E. Shinozaki in 1922 from the leaves of Torreya nucifera.[3] The (−)-isomer was isolated in 1951 by Haagen-Smit and others from Pinus albicaulus.[3] Its structure was determined in 1970 by Lars Westfelt.[4]
Occurrence
δ-Cadinol is produced by the fungus Xylobolus frustulatus as long white needles when grown in malt agar medium.[5] It also occurs in many conifers,[3] and in many other organisms including
- Achillea millefolium (6%) [6]
- Cedrela odorata [3]
- Clitocybe illudens (a mushroom) [1]
- Copaifera multijuga (1%; a major contributor to the aroma of copaiba oil) [7]
- Dictyopteris divaricata (a brown alga) [3]
- Lycaeides argyrognomon (a butterfly; acts as a pheromone) [8]
