摘要: 从狭叶地榆根中分离出7种化合物,经化学和光谱方法鉴定分别为2,4-二羟基-6-甲氧基苯乙酮(Ⅰ)、3,3′,4-三(○-甲基)逆没食子酸(Ⅱ)、3,4′,4-三(○-甲基)逆没食子酸(Ⅲ)、地榆皂甙元(Ⅳ)、地榆皂甙Ⅰ(Ⅴ)、地榆皂甙Ⅱ(Ⅵ)和胡萝卜甙(Ⅶ),其中Ⅰ为首次从天然界中得到,Ⅲ为一新化合物。

关键词: 狭叶地榆, 蔷薇科, 3, 4&prime, 4-三(O-甲基)逆没食子酸, 地榆皂甙

Abstract: Seven compounds (Ⅰ, Ⅱ, Ⅲ, Ⅳ,Ⅴ,Ⅵ,Ⅶ) were isolated from the extract of 80% aqueous ethanol of the roots of Sanguisorba officinalic L.by means of silica gel column and prepared thin layer chromatography.Their structures are elucidated on the basis of chemical and spectral analysis(IR, MS, NMR, UVand elemental analysis), and the comparison with authentic samples and references.They are 2,4-dihydroxy-6-methoxyacetophenone(Ⅰ), 3,3',4-tri (O-methyl)ellagic acid (Ⅱ), 3,4,4'-tri(O-methyl)ellagic acid (Ⅲ), Sanguisorbigenin (Ⅳ), Ziyu-glycoside Ⅰ (Ⅴ), Ziyu-glycoside Ⅱ (Ⅵ) and β-sitosterol-β-D-glucoside (Ⅶ).Among them, Ⅰ is found for the first time from Nature and Ⅲ is a new compound.

Key words: Sanguisorba officinalic L., Rosaceae, 3,4',4-tri(O-methyl)ellagic acid, Ziyu-glycosides
