The Constituents of the Essential Oils from Chrysanthemum boreale and Chrysanthemum makinoi

Abstract

In the course of our chemosystematic investigation of the chrysanthemum native in Japan, the essential oils from Ch. boreale Makino and Ch. makinoi Matsum. et Nakai have been analyzed in detail.
The essential oils were separated into individual components by means of a combination of fractional distillation and preparative GLC or elution chromatography. Thirty compounds were identified on the ground of chemical and spectral evidences. The essential oil from Ch. boreale contains sabinene, a-thujone, pinenes and chrysanthenone as the characteristic compo- nents, while camphene, camphor, borneol and monoterpene esters such as trans-chrysanthenyl, linalyl and bornyl acetate are present in the oil from Ch. makinoi.
