✦ Synopsis

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 (^1^H,^1^H‐COSY, HMQC, HMBC, and NOESY), as well as chemical means.
