New Flavonolignan Glycosides from the Aerial Parts of Zizania latifolia

Two new flavonolignan glycosides, tricin-4'-O-(threo-β-guaiacylglyceryl) ether 7''-O-β-d-glucopyranose (4) and tricin-4'-O-(erythro-β-guaiacylglyceryl) ether 7''-O-β-d-glucopyranose (5) were isolated from the roots of Zizania latifolia, together with tricin-7-O-β-d-gluc...

Sumario:Two new flavonolignan glycosides, tricin-4'-O-(threo-β-guaiacylglyceryl) ether 7''-O-β-d-glucopyranose (4) and tricin-4'-O-(erythro-β-guaiacylglyceryl) ether 7''-O-β-d-glucopyranose (5) were isolated from the roots of Zizania latifolia, together with tricin-7-O-β-d-glucopyranose (1), tricin-4'-O-(threo-β-guaiacylglyceryl) ether 7-O-β-d-glucopyranose (2), and tricin-4'-O-(erythro-β-guaiacylglyceryl) ether 7-O-β-d-glucopyranose (3). Their structures were identified on the basis of spectroscopic techniques, including HR-ESI/MS, 1D-NMR ((1)H, (13)C, DEPT), 2D-NMR (gCOSY, gHSQC, gHMBC), and IR spectroscopy.
