Alstonine is an indole alkaloid and putative antipsychotic constituent of various plant species including Alstonia boonei, Catharanthus roseus, Picralima nitida, Rauwolfia caffra and Rauwolfia vomitoria.
Originally isolated from the plant Rauvolfia serpentina, a medicinal plant widely used in Indian folk medicine, this enzyme participates in terpenoid biosynthesis and indole and ipecac alkaloid biosynthesis, both of which produce many compounds with significant physiological and medicinal properties.
Voacamine, also known under the older names voacanginine and vocamine, is a naturally occurring dimeric indole alkaloid of the secologanin type, found in a number of plants, including Voacanga africana.
N-Formylscholarine is an indole alkaloid isolated from the fruit pods of Alstonia scholaris.
