The epigeal part of Aconitum barbatum gathered in the early vegetation period in the environs of Ulan-Bator has yielded delcosine, lycoctonine, songorine, and the new base bataconine. The structure of bataconine has been shown on the basis of spectral characteristics (IR, NMR, and mass spectra) and also of a correlation with the known alkaloid neoline. © 1988 Plenum Publishing Corporation.
