Two polyacetylene glycosides, gymnasterkoreasides A and B, were isolated from the roots of Gymnaster koraiensis. Their structures were elucidated to be (3R)-8-decene-4,6-diyne-1,3-diol 1-O-β-D-glucopyraside and (3R)-8-decene-4,6-diyne-1,3-diol 1-O-β-D-apiofuranosyl-(1→6)-β-D-glucopyraside on the basis of spectroscopic analysis including COSY, HMQC, and HMBC experiments, as well as chemical methods, which confirmed the determination of a chiral center by the modified Mosher's method.
