Coixlachryside A: A new lignan glycoside from the roots of Coix lachryma-jobi L. var. ma-yuen Stapf.

Publication date: September 2016 Source:Phytochemistry Letters, Volume 17 Author(s): Seong Su Hong, Chun Whan Choi, Yun-Hyeok Choi, Joa Sub Oh 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. Graphical abstract
