| 摘要: |
| 短尾越橘酒精提取物用乙酸乙酯萃取后依次经氯仿、丙酮、甲醇回流提取,用薄层层析,反复硅胶柱层析,从中分离并鉴定了八个化合物,并用波谱学方法进行了结构鉴定。它们分别为正二十七烷(n-heptacosane,Ⅰ),木栓酮(friedelin,Ⅱ),木栓醇(friedelinol,Ⅲ),羽扇豆醇(lupenol,Ⅳ),β-谷甾醇(β-sitosterol,Ⅴ),胡萝卜苷(dauosterol,Ⅵ),反式对羟基桂皮酸(trans-p-hydroxy cinamic acid,Ⅶ),莽草酸甲酯(methyl shikimate,Ⅷ)。所有化合物均为首次从该植物中分离得到,化合物Ⅰ,Ⅳ,Ⅷ为首次从该属植物中得到。 |

| Abstract: |
| The extractive of Vaccinium carlesii with alcohol was extracted by acetic ether and then abstracted by chloroform,acetone and methanol by turns. The chemical constituents were isolated by using repeated silical gel column chromatography. 8 compounds were isolated and identified. Their structures were determined by spectral means. They were n-heptacosane(Ⅰ),friedelin(Ⅱ),friedelinol(Ⅲ),lupenol(Ⅳ),β-sitosterol(Ⅴ),dauosterol(Ⅵ),trans-p-hydroxy cinamic acid(Ⅶ)and methyl shikimate(Ⅷ). All the compounds were obtained from this plant for the first time. Compounds Ⅰ,Ⅳ,Ⅷ are newly isolated from the plant of Vaccinium. |
