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。
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-/3-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 t-test time. Compound 1 is isolated from this plant for the first time.
