摘要：
In addition to (-)-mehranine, hecubine, ibogaine, ibogaline, 19R-epi voacristine, 20-hydroxyconopharyngine and pedunculine the novel indole alkaloids 3-oxomehranine and 14 alpha,15 beta-dihydroxy-N-methylaspidospermine have been isolated from the leaves and stems of Tabernaemontana bovina. The structure of 3-oxomehranine has been assigned by NMR investigations, the structure of 14 alpha,15 beta-dihydroxy-N-methylaspidospermine by X-ray analysis and their absolute configurations by circular dichroism.
