Ungernia victoris

Several substances have been detected in the course of Amarylli-daceae alkaloid isolations which cannot be classified within any of the previous sections. Of these, belladine and 0-methylnorbelladine are basic substances of singular importance in the biosynthesis of the alkaloids of the family. Further discussion of these bases is reserved for Section X. Hordenine has been isolated from Pancratium maritimum (3) and Ungernia victoris (61). It appears to be a metabolite of tyrosine, an important amino acid percursor of the alkaloids of the family. Ismine, C15H15NO3 (mp 99.5°-100.5° [a]p +0° in CHCI3 picrate, mp 158°-159°), has been isolated from an unidentified Ismene spp., Crinum powellii, and Sprekelia formosissima in minute amounts (6). [Pg.382]
