A phytochemical study of the roots and rhizomes of Veratrum viride led
to the isolation of the two new steroidal alkaloids, rubivirine, iden
tified as 12 beta-hydroxyisorubijervine, and veramivirine, identified
as 12 beta-hydroxyveramiline. Structural elucidation of the two compou
nds was aided by 2D-NMR spectral analyses.
