Two novel sorghumol acyl esters, sorghumol 3‐ O‐Z‐p ‐coumarate and sorghumol 3‐ O‐E‐p ‐coumarate, and a novel alkaloid, anoectochine, were isolated from the whole plants of Anoectochilus roxburghii along with one known triterpenoid, sorghumol. Their structures were established by their detailed spectral studies, including two‐dimensional NMR ( 1 H– 1 H COSY, HSQC and HMBC). Copyright © 2008 John Wiley & Sons, Ltd.
