| 摘要: |
| 通过多种柱色谱对龙眼壳中多酚类成分进行分离纯化及结构鉴定。结果表明:从中得到6个多酚类化合物,根据波谱数据分析及文献对比,分别鉴定为原儿茶酸(1)、没食子酸(2)、1,2,3,4,6-O-五没食子酰葡萄糖(3)、柯里拉京(4)、乙酰甲基-老鹳草素(5)、(-)-表儿茶素(6)。所有化合物均为首次从该植物中分离得到 |

| Abstract: |
| The chemical constituents of Dimocarpus longan pericarp were isolated and purified by Sephadex LH-20,MCI gel CHP 20P,and Toyopearl Butly-650C column chromatography and yield six polyphenol compounds. Their structures were elucidated by NMR and literature as:3,4-dihydroxybenzoic acid(1),gallic acid(2),1,2,3,4,6-penta-O-galloyl-β-D-glucose(3),corilagin(4),acetonylgeraniin(5),(-)-epicatechin(6). All compounds were isolated from the D. longan Pericarp for the first time. |
