eucalyptol \eu`ca*lyp*tol\, n. [eucalyptus + L. oleum oil.]
(Chem.)
A volatile, terpenelike oil ({C10H18O}), which is the main
constituent of the oil of eucalyptus. It has cockroach
repellent activity and is used as a flavoring aid in
pharmaceuticals. Chemically it is
1,3,3-trimethyl-2-oxabicyclo-[2,2,2]-octane. --MI11

Syn: cineole, cajeputol. [1913 Webster +PJC]

Note: In the 1913 Webster eucalytpol was defined as an oil
``consisting largely of cymene''. Cymene
(isopropyltoluene, {C10H14}) differs from that of the
substance currently called eucalyptol, in having an
unsaturated ring and no oxygen. Para-cymene does occur
in eucalyptus oil as well as some other essential oils.
