Abstract
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).
