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 an epimer of α-cadinol.

δ-Cadinol exists in nature as either of two enantiomers distinguished by the prefixes (+)- and (−)-.[1][2] The (+)-isomer was identified by E. Shinozaki in 1922 from the leaves of Torreya nucifera and originally named torreyol.[1] The (−)-isomer was isolated in 1951 by Haagen-Smit and others from Pinus albicaulus and first called albicaulol.[1] Its structure was determined in 1970 by Lars Westfelt.[2] Other names were given to δ-cadinol based on its various biological sources before the structures were confirmed, including sesquigoyol for (+)-δ-cadinol and pilgerol for (−)-δ-cadinol.[2][3] Lambertol is thought to be either (+)-δ-cadinol or (−)-δ-cadinol.[2] Cedrelanol was originally thought to be identical to (−)-δ-cadinol but was later confirmed to have the structure of τ-cadinol.[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,[1] and in many other organisms including
