【摘要】 采用乙醇提取,硅胶柱层析分离和波谱方法鉴定结构,从大叶盘果菊(Prenanthes macrophylla Franch)中初步分离鉴定出8个化合物:木栓酮(friedelin,1)、木栓醇(friedelanol,2)、α-香树脂醇(α-amyrin,3)、α-香树脂醇乙酸脂(α-amyrin acetate,4)、β-香树脂醇乙酸酯(β-amyrin acetate,5)、蒲公英甾醇乙酸酯(taraxasteryl acetate,6)、β-谷甾醇(β-sitosterol,7)、二十八烷酸(octacosanoic acid,8),这些化合物均为首次从该植物中分离得到。更多还原

【Abstract】 Eight compounds were isolated from the ethanol extract of Prenanthes macrophylla Franch.and identified as friedelin,friedelanol,α-amyrin,α-amyrin acetate,β-amyrin acetate,taraxasteryl acetate,β-sitosterol,and octacosanoic acid.Their structures were determined on the basis of chemical evidence and spectral data.These compounds were isolated from this plant for the first time.更多还原
