A study of alkaloids in Veratrum viride Aiton

The phytochemical study of Veratrum viride (Liliaceae) roots and rhizomzes led to the isolation of 5 alkaloids reported for the first time in this species viz. veramarine [1], angeloylzgadenine [4] zygadenine [6], 15-O-methylbutyroylgermine [8], and 1 alpha, 3 beta-dihydroxy 5 alpha-jervanin-12-en-11-one [9]. The well known alkaloids veratramine [2], jervine [3], isorubijervine [5], germine [7], rubijervine [10], and pseudojervine [11] were also isolated in the course of this effort. The identification of all compounds was aided significantly Dy 2D-NMR spectral analyses.
