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. |
