Camphene is a solid terpene. The dextro variety d-camphene is found in camphor, ginger and spike oils, and the levo variety, 1-camphene is in citrondla and valerian oil and in French and American turpentine. Bornylene does not occur in nature but has been prepared from the alcohol corresponding to it known as Borneol or Borneo camphor. This, as previously stated, may be prepared from pinene so that Bornylene itself may be made from pinene. Fenchene, also, is not found in nature but is obtained by reduction of fenchone a terpene ketone found in fennel oil and in Thuja oil. 

The most important of all of the oxygen derivatives of the terpene hydrocarbons are those of the di-cyclic group. Of these the most common is the well-known substance camphor, also termed Japan camphor. It is a ketone derivative of a di-cyclic terpene of the cam-phane type known as Bomylene. The corresponding alcohol derivative is known as Bomeol, or Borneo camphor. 

Bomeol—Borneo camphor—Campkol—Camphyl alcohol—— 164—ia usually obtained from dryoManOfe camphora, although it may bo obtained from other plants, and even artificially hy the hydrogenation of laurel camphor. The product from these diflereut sources is the same chemically, so frur as we can determine, but varies, like the modificationa of camphor, in its action on polarized light.

Naturally occurring camphanes include the bomeols with an endo hydroxy group, the isobomeols with an exo OH and 2-camphanone (2-bonanone) referred to as camphor. (+)-Bomeol from the camphor tree Cinnamomum camphora (Lauraceae) and from the roots of ginger-like Curcuma aromatica (Zingiberaceae), both of which grow in Eastern Asia, is known as Borneo camphor. (-)-Isobomeol was isolated from Achillea filipendulina (Asteraceae).

Berthelot obtained new alcohols from cholesterol, ethal, Borneo camphor, meconine, etc. He defined alcohols as neutral compounds of carbon, hydrogen, and oxygen which with acids form, with elimination of water, neutral compounds which are capable of taking up the elements of water to form the two substances from which they were produced. He similarly first constituted the group of phenols. ...

The wood of Dryobalanops aromatka, or Borneo camphor tree, yields this essential oil. The tree is a native of Sumatra and North-West Borneo, but its essential oil is rarely seen in commerce.
