Abstract
CONDENSATION of nitromeconine and hydrastinine gave a mixture of nitrohydrastines, which was reduced and the product separated into aminohydrastines-a and -b 1. By the removal of the ammo-groups, dl-hydrastine-a (m.p. 137°) and dl-hydrastine-b (m.p. 150–51°) were obtained, but at that time neither of these inactive stereoisomerides could be resolved.
