Atropa belladonna
Cuscohygrine is a pyrrolidine alkaloid found in coca. It can also be extracted from plants of the family Solanaceae, including "Atropa belladonna" (deadly nightshade), "Datura innoxia" and "Datura stramonium" (jimson weed). Cuscohygrine usually occurs along with other, more potent alkaloids such as atropine or cocaine.
