【摘要】 目的对苦荞麦〔Fagopyrum tataricum(L.)Gaertn.〕的种子中的化学成分进行研究。方法采用硅胶柱色谱等方法进行分离纯化,根据理化性质和光谱数据进行结构鉴定。结果分离得到11个化合物,分别鉴定为乌苏酸(ursolic acid,1)、山柰酚(kaempferol,2)、槲皮素(quercetin,3)、大黄素(emodin,4)、山柰酚-3-O-芸香糖苷(kaempferol-3-O-rutinoside,5)、芦丁(rutin,6)、3′,5′-二甲氧基-4′-O-β-D-吡喃葡萄糖基桂皮酸(3′,5′-dimethoxy-4′-O-β-D-glucopyranosyl-cinnamic-acid,7)、β-谷甾醇(β-sitosterol,8)、胡萝卜苷(daucosterol,9)、蔗糖(sucrose,10)、果糖(fructose,11)。结论化合物7是从荞麦属中首次分离得到,化合物1是从该植物中首次分离得到。更多还原

【Abstract】 Objective To study chemical constituents from the seeds of Fagopyrum tataricum(L.)Gaertn..Methods The compounds were isolated by chromatography on silica gel columns and identified by their physical-chemical properties and spectral analysis.Results Eleven compounds were obtained and identified as ursolic acid(1),kaempferol(2),quercetin(3),emodin(4),kaempferol-3-O-rutinoside(5),rutin(6),3′,5′-dimethoxy-4′-O-β-D-glucopyranosyl-cinnamic acid(7),β-sitosterol(8),daucosterol(9),sucrose(10),fructose(11),respectively.Conclusions Compound 7 is isolated from Fagopyrum genus for the first time.Compound 1 is isolated from this plant for the first time.更多还原
