Four known aporphine alkaloids, boldine, norboldine, laurotetanine and
lindecarpine were isolated from the bark of Phoebe grandis. The leave
s yielded two new alkaloids belonging to the proaporphine-tryptamine d
imers series, phoebegrandines A and B. The structure of the new compou
nds was elucidated by spectral methods. (C) 1997 Elsevier Science Ltd.
