Bulbocapnine is an alkaloid found in Corydalis (Papaveraceae) and Dicentra, plants in the family Fumariaceae that can cause fatal poisoning in sheep and cattle. It has been shown to act as an acetylcholinesterase inhibitor, and inhibits biosynthesis of dopamine via inhibition of the enzyme tyrosine hydroxylase.
