Résumé

Indolic alkaloid

K-562

Psychotria prunifolia

Psychotriae

Rubiaceae

S-180

Two new quaternary β-carboline alkaloids, were isolated from the aerial parts of Psychotria prunifolia (Kunth) Steyerm., collected in Goiás, Brazil, and their structures were determined by NMR analysis. Two new quaternary alkaloids, compound 1 and the 14-oxo derivative 2, were isolated along with the known alkaloid strictosamide ( 3) from the leaves of Psychotria prunifolia (Kunth) Steyerm. (Rubiaceae, Psychotriae). Their structures were elucidated using spectroscopic methods (1D and 2D NMR, IR, and HRMS).
