Coca alkaloids

Hygrine is a pyrrolidine alkaloid, found mainly in coca leaves (0.2%). It was first isolated by Carl Liebermann in 1889 (along with a related compound cuscohygrine) as an alkaloid accompanying cocaine in coca. Hygrine is extracted as a thick yellow oil, having a pungent taste and odor.

Cuscohygrine is a bis N-methyl pyrrolidine alkaloid found in coca plants. It can also be extracted from plants of the family Solanaceae, including Atropa belladonna (deadly nightshade) and various Datura species. Cuscohygrine usually occurs along with other, more potent alkaloids such as atropine or cocaine.
