Chemistry for Everyone
Two Faces of Alkaloids
Jirí Dostál

Abstract
Alkaloids can occur in two forms, denoted as ammonium salts and free bases. These forms differ substantially in their properties and in some cases in their structures. The article discusses and compares the salts and free bases of six well-known alkaloids: nicotine, morphine, cocaine, sanguinarine, allocryptopine, and magnoflorine. Relevance for the biological and medical uses of these compounds is emphasized.
