【摘要】 目的研究浮萍Spirodela polyrrhiza(L.)Schleid.的化学成分。方法采用正相和反相硅胶柱色谱以及半制备型HPLC进行分离纯化,根据理化性质和波谱数据鉴定化合物的结构。结果分离得到了5个黄酮苷类化合物,分别鉴定为芹菜素8-C-(2″-O-阿魏酰基)-β-D-葡萄糖苷(apigenin-8-C-(2″-O-feruoyl-)-β-D-glucoside,1),荭草素(rietin,2),牡荆素(vitexin,3),木犀草素7-O-β-D-葡萄糖苷(luteolin7-O-β-D-glucoside,4),芹菜素7-O-β-D-葡萄糖苷(apigenin7-O-β-D-glucoside,5)。结论化合物1为一个新化合物,化合物2和3为首次自该植物中分离得到。更多还原

【Abstract】 Objective To study the chemical constituents of the whole plant of Spirodela polyrrhiza(L.)Schleid..Methods The compounds were isolated by silica gel and ODS column chromatography and semi-preparative HPLC,their structures were elucidated on the basis of their physicochemical and spectroscopic data.Results Five compounds were obtained from S.polyrrhiza.Their structures were identified as apigenin 8-C-(2″-O-feruoyl)-β-D-glucoside(1),rietin(2),vitexin(3),luteolin 7-O-β-D-glucoside(4)and apigenin 7-O-β-D-glucoside(5).Conclusions Compound 1 is a new compound.Compounds 2 and 3 were isolated from this plant for the first time.更多还原
