Chemical studies
The diterpenoid alkaloids lycoctonine and tricornine (otherwise known as lycoctonine-18-O-acetate) have been isolated from D. tricorne. The toxicology and pharmacology of lycoctonine have been quite well studied, but there is only limited information available concerning the biological properties of tricornine. Both alkaloids have neuro-muscular blocking properties, and D. tricorne should be treated as a potentially poisonous plant. This species has long been regarded as poisonous to livestock.
