Dryobalanops Camphora

Borneol \Bor"ne*ol\, n. [Borneo + -ol.] (Chem.)
   A rare variety of camphor, {C10H17.OH}, resembling ordinary
   camphor, from which it can be produced by reduction. It is
   said to occur in the camphor tree of Borneo and Sumatra
   ({Dryobalanops camphora}), but the natural borneol is rarely
   found in European or American commerce, being in great
   request by the Chinese. Called also {Borneo camphor}, {Malay
   camphor}, and {camphol}.

   The genus to which belongs the single species {Dryobalanops
   Camphora}, a lofty resinous tree of Borneo and Sumatra,
   yielding Borneo camphor and camphor oil.

Camphor \Cam"phor\ (k[a^]m"f[~e]r), n. [OE. camfere, F. camphre
   (cf. It. canfora, Sp. camfora, alcanfor, LL. canfora,
   camphora, NGr. kafoyra`), fr. Ar. k[=a]f[=u]r, prob. fr. Skr.
   karp[=u]ra.]
   1. A tough, white, aromatic resin, or gum, obtained from
      different species of the {Laurus} family, esp. from
      {Cinnamomum camphara} (the {Laurus camphora} of
      Linn[ae]us.). Camphor, {C10H16O}, is volatile and
      fragrant, and is used in medicine as a diaphoretic, a
      stimulant, or sedative.
      [1913 Webster]

   2. originally, a gum resembling ordinary camphor, obtained
      from a tree ({Dryobalanops aromatica} formerly
      {Dryobalanops camphora}) growing in Sumatra and Borneo;
      now applied to its main constituent, a terpene alcohol
      obtainable as a white solid {C10H18O}, called also {Borneo
      camphor}, {Malay camphor}, {Malayan camphor}, {camphor of
      Borneo}, {Sumatra camphor}, {bornyl alcohol}, {camphol},
      and {borneol}. The isomer from {Dryobalanops} is
      dextrorotatory; the levoratatory form is obtainable from
      other species of plants, and the racemic mixture may be
      obtained by reduction of camphor. It is used in perfumery,
      and for manufacture of its esters. See {Borneol}.
      [1913 Webster +PJC]

   Note: The name camphor is also applied to a number of bodies
         of similar appearance and properties, as {cedar
         camphor}, obtained from the red or pencil cedar
         ({Juniperus Virginiana}), and {peppermint camphor}, or
         {menthol}, obtained from the oil of peppermint.
         [1913 Webster]

   {Camphor oil} (Chem.), name variously given to certain
      oil-like products, obtained especially from the camphor
      tree.

   {Camphor tree}, a large evergreen tree ({Cinnamomum
      Camphora}) with lax, smooth branches and shining
      triple-nerved lanceolate leaves, probably native in China,
      but now cultivated in most warm countries. Camphor is
      collected by a process of steaming the chips of the wood
      and subliming the product.
