Epimeric (20R,20S)-Verazine Isolated from Veratrum maackii: Two-Dimensional NMR Studies and Total Assignment of 1H- and 13C-Resonances

, : Epimeric (20R,20S)-Verazine Isolated from Veratrum maackii: Two-Dimensional NMR Studies and Total Assignment of 1H- and 13C-Resonances. Planta Medica 58(5): 449-453

The alkaloid verazine ((25S)-iminocholesta-5,22(N)-diene-3 beta -ol) was isolated from V. maackii (collected from China) and found to consist of a 20R/20S mixture of epimers.
