Peduncularistine, Triabunnine and Aristolarine, Three Ne Indole Alkaloids from Aristotelia peduncularis (L LABILL .) H OOK , F. Peduncularistine ( 1 ), triabunnine ( 2 ) and aristolarine ( 3 ), three new indole alkaloids, have been isolated from Aristotelia peduncularis (L ABILL. ) H OOK . F.; the structure and absolute configuration of 1 were elucidated on the basis of spectroscopic data and confirmed byt transformation of 1 into aristeserratine ( 4 ), a known alkaloid isolated from the same plant. The proposed structure 2 for the second alkaloid and its absolute configuration were established but spectroscopic means and by partial synthesis from 4 . The relative configuration of 3 was postulated on the basis of spectroscopic and biogenetic arguments.
