## Abstract magnified image Four new __Daphniphyllum__ alkaloids, daphlongamines EβH (**1**β**4**, resp.), along with 19β known alkaloids, were isolated from the leaves of __Daphniphyllum longeracemosum.__ Their structures were characterized by spectroscopic methods, especially 2DβNMR techniques. I
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-
