摘要：

The structures of tabernaelegantines A-D and tabernaelegantinines A and B, new dimeric indole alkaloids isolated from the root bark of T. elegans Stapf., were determined from their IR, UV, mass spectra, and 1H and 13C NMR spectra. The structural elucidation required the analysis of the 13C spectra of voacangine, dregaminol and tabernaemontanol. The 13C NMR investigation supports the revision of the reported configurations at C-20 of dregamine and tabernaemontanine.
