✦ Synopsis

The structure of veracintine the novel alkaloid isolated from the aboveground part of Veratrum album subsp. lobelianum (Bernh.) has been inferred basing upon the study of n.m.r., i.r., U.V. and mass spectra of its and its derivatives. Veracintine, 20-(2-methyl-l-pyrrolin-5-yl)-pregn-5-ene-3fJ-ol, is shown to be a novel structural type of a biogenetically interesting veratrum alkaloid.

Veracintine (I), mop. 196-201°,[d]G5 +7.S" (chloroform) shows in its mass

Bioassay-guided fractionation of the ethanol extract of the roots and rhizomes of Veratrum taliense yielded two new and thirteen known steroidal alkaloids. The structures of the two new compounds, neoverataline A and B, were established by extensive spectroscopic analyses to be 3,4-secocevane-4, 9-o

Some years ago, Tomko et al. (I) isolated a secondary alkaloid, veralkamine, from Veratrum album ssp. lobelianum (Bernh.) Suessenguth. In alteration of a formerly proposed provisional constitution (2) its complete structure has been established by recent chemical and physical reinvestigations includ
