Coniferyl alcohol is a phenylpropanoid . It is the aglycon of coniferin and a component of softwood - lignin .
Extraction
Theodor Hartig was first able to characterize it in 1861 in the cambial sap of the larch. The Holzminden pharmacist Wilhelm Kubel identified the glucoside of coniferyl alcohol in 1866. It was first obtained in 1874 by F. Tiemann and W. Haarmann by acid hydrolysis of the glucoside coniferin or today by the enzyme emulsin (a β- glucosidase ).
biochemistry
Coniferyl alcohol is a metabolic intermediate in the biosynthesis of eugenol .
