  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.
