Research ArticlesSabadilla Alkaloids VIII: Isolation of SABADILLINE (cas 1415-76-5)s I, II, and III

Add time:09/24/2019    Source:sciencedirect.com

The techniques of partition and adsorption chromatography as well as counter-current distribution have been applied to alkaloidal concentrates from both sabadilla and veratrine. Whereas sabadilline previously was considered to consist of a single alkaloidal constituent, the present work has resulted in the isolation of three different materials which possess the characteristic ultraviolet absorption maximum at 238 mμ. These materials have been named sabadilline I, II, and III. Only sabadilline II was obtained in crystalline form. Attempts to establish a relationship between the three compounds were unsuccessful. Only sabadilline II yielded an alkaline isomerization product and this was not similar to either sabadillines I or III.
