Studies in Plant Chemistry. I. The Essential Oils of Eucalyptus caesia Benth. and E. torquata Luehm. and the Structure of Torquatone

Abstract

A preliminary study of the essential oils of Eucalyptus caesia Benth, and E. torquata Luehm. has revealed the presence of a common ketonic substituent C₁₆H₂₄O₄. On the basis of degradative work described, the new substance, torquatone, has been assigned structure II, [2,4,6-trimethoxy-3,5-dimethyl]benzyl isopropyl ketone.
