Abstract

Two new 3-aminospirosolane steroidal alkaloids, (22S,25S)-3 alpha-amino-5 alpha-spirosolane and (22S,25S)-3 beta-aminospirosol-5-ene, along with the known soladunalinidine were isolated from the alkaloid fraction of a methanol extract of Solanum arboreum. Their structures were determined by a combination of 1D and 2D NMR techniques and mass spectrometry. Copyright (C) 1996 Elsevier Science Ltd.
