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‐data analysis, by chemical derivatization, and by comparison of their spectroscopic data with those of known compounds.
