抄録

Structures of the new indole alkaloids, 19- (Z) -akuammidine, 16-epi-voacarpine, 19-hydroxydihydrogelsevirine isolated from the root of Gelsemium elegans have been determined by the spectral method, X-ray analysis and chemical correlation. Koumidine was revised to show the 19- (Z) ethylidene configuration in the structure.
