Abstract Three new psychollatine-derived monoterpene indole alkaloids were obtained from Psychotria umbellata Thonn.: 3,4-Dehydro-18,19-β-epoxy-psychollatine ( 2 ), N 4 -[1-(( R )-2-hydroxypropyl)]-psychollatine ( 3 ), and N 4 -[1-(( S )-2-hydroxypropyl)]-psychollatine ( 4 ). Their structures were determined by 1 H and 13 C NMR spectra, 2D correlations (COSY, HMQC, and HMBC), and mass and UV spectra. Compounds 3 and 4 were synthesized for structural confirmation and for the determination of the… CONTINUE READING
