Abstract:
Lumusidines A–D, bisindole alkaloids of the macroline–macroline type, and one of the macroline–pleiocarpamine type, villalstonidine F, were isolated from the stem-bark extract of Alstonia macrophylla (Apocynaceae). The structures and absolute configurations of these alkaloids were established using NMR, MS, and X-ray diffraction analyses.
