Three phenolic glycosides 5-O-{[5''-O-E-(4'''-O-threo-guaiacylglycerol)-feruloyl]-beta-apiofuranosyl-(1-->2)-beta-xylopyranosyl} gentisic acid, 5-O-[(5''-O-vanilloyl)-beta-apiofuranosyl-(1-->2)-beta-xylopyranosyl] gentisic acid and 1-O-[E-(4'''-O-threo-guaiacylglycerol)-feruloyl]-3-O-beta-galacturonopyranosyl glycerol were isolated and identified from the roots of Medicago truncatula together with four known 5-O-beta-xylopyranosyl gentisic acid, vicenin-2, hovetrichoside C and pterosupin identified for the first time in this species. Structural elucidation was carried out on the basis of UV, mass, (1)H and (13)C NMR spectral data.
从蒺藜苜蓿根部分离并鉴定出三种酚苷,分别为5-O-{[5''-O-E-(4'''-O-苏式-愈创木基甘油基)-阿魏酰基]-β-芹菜糖基-(1→2)-β-木糖基}龙胆酸、5-O-[(5''-O-香草酰基)-β-芹菜糖基-(1→2)-β-木糖基]龙胆酸和1-O-[E-(4'''-O-苏式-愈创木基甘油基)-阿魏酰基]-3-O-β-半乳糖醛酸基甘油,同时还鉴定出四种已知的5-O-β-木糖基龙胆酸、异荭草苷-2、霍韦特里乔苷C和翼籽苏品,其中后四种为首次在该物种中鉴定出。基于紫外、质谱、1H和13C NMR光谱数据进行了结构解析。
