| 摘要: |
| 采用Sephadex LH-20、MCI gel CHP 20P和Toyopearl Butly-650C等柱色谱,反复对80%乙醇荔枝皮提取物进行分离、纯化,得到7个多酚类化合物。根据波谱分析以及文献数据对比,分别鉴定为对羟基苯甲酸(1)、原儿茶酸(2)、(+)儿茶素(3)、(-)表儿茶素(4)、原花青素A2(5)、aesculitannin A(6)、槲皮素-3-O-β-D-葡萄糖苷(7)。除5以外的化合物均为首次从荔枝果皮中分离得到。 |

| Abstract: |
| The 80% ethanol extracts of the Litchi chinensis pericarp was isolated and purified by Sephadex LH-20,MCI gel CHP 20P,Toyopearl Butly-650C column chromatography to yield seven phenolic compounds. Their structures were identified by the analysis of spectral data as:p-Hydroxybenzoic acid(1),3,4-dihydroxybenzoic acid(2),(+)-catechin(3),(-)-epicatechin(4),procyanidin A2(5),aesculitannin A(6),quercetin-3-O-β-D-glucopyranoside(7). All the compounds except 5 were reported from L. chinensis pericarp for the first time. |
