WOLTER FILHO, Wilson; ANDRADE, Carlos Humberto Souza; BRAZ FILHO, Raimundo  and  MATOS, Francisco José de Abreu. Alcalóides de Peschiera affinis (Muell. Arg) Miers (Apocynaceae). Acta Amaz. [online]. 1985, vol.15, n.1-2, pp.193-198. ISSN 1809-4392.

The methanolic extracts of bark and woody roots from three especimens of Peschiera affinis (Apocynaceae) collected at different geographical sites (Fortaleza , Ubajara-CE e Cical-PI) afforded, after chromatographical separation, the following alkaloids: coronanidine, epiheyneanine, affinisine, vobasine, olivacine, voacangine, voacristine, iboxygaine and l9-hidroxi-ibogamine. The latter four substances were found previously in the genus Tabernanthe and Voacanga and are registered here for Peschiera affinis for the first time.
