Abstract
The genus Psychotria (Rubiaceae) comprises more than 2000 species, mainly found in tropical and subtropical forests. Several studies have been conducted concerning their chemical compositions, showing that this genus is a potential source of alkaloids. At least 70 indole alkaloids have been identified from this genus so far. This review aimed to compile (13)C-NMR data of alkaloids isolated from the genus Psychotria as well as describe the main spectral features of different skeletons.
