Two new complex polycyclic alkaloids, macropodumines D (
1) and E (
2), both possessing unprecedented skeletons, along with f
our knownrelated alkaloids, were isolated from the leaves and barks of
Daphniphyllum macropodum Miq. The structures including the relativestereochemistry of new comp
ounds
1 and
2 were elucidated on the basis of detailed spectroscopic data analysis.
