Abstract

Two new iridoid alkaloids, daphmacropodosidines A (1) and B (2), together with two known ones, daphcalycinosidine B and caldaphnidine F, were isolated from the fruits of Daphniphyllum maropodum. Their structures were established by spectral methods, especially 2D NMR spectra (1H,1H-COSY, HMQC, HMBC, and NOESY), as well as chemical means. © 2007 Verlag Helvetica Chimica Acta AG.
