   • 1894, Charles E. Sohn, Dictionary of the Active Principles of Plants:

     The name Amaroid is suggested for such bodies as these, in order to avoid confusion with glucosides and alkaloids, so many of which are also bitter.

   • 1895, Bulletin of pharmacy, volume 9, page 374:

     Picrotoxin is classed by Schon as an amaroid or bitter principle, although by some it is looked upon as a glucoside.
