The organic extracts of leaves and roots of Psychotria stachyoides provided the new glucoside monoterpenoid indole alkaloid N-demethylcorreantoside, besides bizantionoside B, α-amyrin, alizarine methyl-ether, rubiadine, scopoletin, barbinevic acid and a mixture of β-sitosterol and stigmasterol glucosides. The structural characterization of the isolates was established based on infrared spectroscopy (IR), mass spectrometry (MS) and, particularly, 1D and 2D nuclear magnetic resonance (NMR).
