Abstract
A new lignan glycoside, 1-[3,6-(4,4′-dihydroxy-3,3′-dimethoxy-δ-truxinyl)-β-fructofuranosyl]-α-glucopyranoside (1), named coixlachryside A, together with nine known simple phenolic compounds (3–11) were isolated from the roots of Coix lachryma-jobi var. ma-yuen using various chromatographic methods. Their chemical structures were determined based on the spectroscopic data interpretation, particularly circular dichroism (CD), 1D and 2D NMR data including HSQC and HMBC.
