Abstract

Five new polycyclic Daphniphyllum alkaloids, macropodumines F (1) and G (2), 17‐oxoyuzurimine (3), and macropodumines H (4) and I (5), were isolated from the leaves of D. macropodum Miq., collected in Sichuan Province, China. The structures and relative configurations of the new compounds – as well as of four known, related alkaloids – were elucidated on the basis of in‐depth spectroscopic and mass‐spectrometric analyses, by chemical derivatization, and by comparison of spectroscopic data with those of known compounds.

Two new Daphniphyllum alkaloids, 9,10-epoxycalycinine A (1) and homodaphniphyllate (2), together with eight known related alkaloids, were isolated from the stems and leaves of Daphniphyllum calycinum. The structures of the new compounds 1 and 2 were elucidated on the basis of in-depth spectroscopic-
