Abstract: Twelve undescribed bisindole alkaloids, tabernaemontines A–L, were simultaneously isolated from the leaves of Tabernaemontana bovina and their structures were elucidated by spectroscopic methods. All alkaloids consist of two Aspidosperma-type units with various intramolecular linkages. Particularly,… read more here.

DOI: 10.1080/10286020.2022.2090345
Abstract: Abstract Two new aspidosperma-type monoterpenoid indole alkaloids, 16-O-methylvoafinine (1) and 14,15-diepi-voafinidine (2) were isolated from the aerial parts of Ervatamia officinalis. Their structures were established by comprehensive spectroscopic analysis including 1D and 2D NMR, HR-ESI-MS,… read more here.
