- n. The aromatic principle of coffee.
Sorry, no etymologies found.
The main effects of coffee are due to both the caffeine and the caffeone, which are antagonistic, though not contemporaneous, in action.
This elusive material has been variously called caffeol, caffeone, "the essential oil of coffee," etc., the terms having acquired an ambiguous and incorrect significance.
"empyreumatic oil of coffee, _caffeone_," is active; but more recent investigations have yielded results at variance with this.
Later, Graham, Stenhouse, and Campbell started on the way to the identification of this aroma by noting that "in common with all the valuable constituents of coffee, caffeone is found to come from the soluble portion of the roasted seed." [
