Abstract
Investigation of an ethanolic extract of the fresh flowers of Hippeastrum vittatum yielded the new alkaloids vittacarboline (1) and O-methylismine (3), together with the known compound ismine (2). The structures of 1--3 were established by spectroscopic methods including one- and two-dimensional NMR and mass spectrometry.
