Abstract

Pyrrole-3-carbamidine has been isolated and identified as the lethal constituent of Nierembergia hippomanica. An oxindole alkaloid, Nb-demethylalstophylline oxindole has been isolated from the leaves of Alstonia macrophylla. Its structure has been elucidated on the basis of spectroscopic studies.
