Abstract

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 (1H, 13C, DEPT), 2D-NMR (gCOSY, gHSQC, gHMBC), and IR spectroscopy.

摘要

从茭白根部分离出两种新的黄酮木脂素糖苷，即小麦黄素-4'-O-(苏式-β-愈创木基甘油基)醚7''-O-β-D-吡喃葡萄糖苷(4)和小麦黄素-4'-O-(赤式-β-愈创木基甘油基)醚7''-O-β-D-吡喃葡萄糖苷(5)，以及小麦黄素-7-O-β-D-吡喃葡萄糖苷(1)、小麦黄素-4'-O-(苏式-β-愈创木基甘油基)醚7-O-β-D-吡喃葡萄糖苷(2)和小麦黄素-4'-O-(赤式-β-愈创木基甘油基)醚7-O-β-D-吡喃葡萄糖苷(3)。它们的结构通过光谱技术得以鉴定，这些技术包括高分辨电喷雾电离质谱(HR-ESI/MS)、一维核磁共振(1H、13C、DEPT)、二维核磁共振(gCOSY、gHSQC、gHMBC)以及红外光谱(IR)。
