+"In the commercial exploitation of Eucalyptus dives oil... for the separation of piperitone, large quantities of phellandrene are obtained as a by-product. This substance possesses valuable solvent properties and finds use in the preparation of a number of proprietary liquids for solvent purposes, and has been carefully refined by the fine chemical manufacturers of London when the pine odour developed through purification has been found
+suitable for certain classes of soap perfumes." \\

+Major components of the essential oils of chemical varieties of Eucalyptus dives ("Type", "Var. A", "Var. B", and "Var. C") of //Eucalyptus dives// were piperitone, 1.8-cineole, and α-phellandrene. \\
