【摘要】 通过硅胶柱层析、凝胶柱层析等色谱方法,从水杨梅植物全草乙醇提取物的乙酸乙酯部分中分离出5种化合物,其结构经波谱分析和化学分析,鉴定为山奈酚(1)、槲皮素(2)、山奈酚-3-O-葡萄糖苷(3)、槲皮素-3-O-葡萄糖苷(4)、胡萝卜苷(5)。其中化合物1～4为首次从该植物中分离得到。更多还原

【Abstract】 By using chromatographic technology,five compounds were isolated from the ethyl acetate extract obtained by partitioning the ethanolic extract from the whole plant of Geum aleppicum.The structures of these compounds were elucidated by spectral data and chemical reaction as kaempferol(1),quercetin(2),kaempferol-3-O-glucoside(3),quercetin-3-O-glucoside(4) and daucosterol(5).The compounds 1-4 were isolated from Geum aleppicum for the first time.更多还原
