Chemical study of the leaves and stem bark of Ervatamia peduncularis a
fforded two novel bisindole alkaloids, pedunculine and peduncularidine
, together with seven known alkaloids, coronaridine, coronaridine hydr
oxyindolenine, eglandine, heyneanine, eglandulosine, heyneanine hydrox
yindolenine and N(1)-methyl-aspidospermidine. Structural elucidation o
f the new alkaloids was based on their spectral data.
