| 摘要: |
| 采用80%丙酮提取物的水萃取部位,利用凝胶、MCI、反相碳18、及Toyopearl Butyl-650C柱色谱进行分离纯化得到7个黄酮和3个苯乙醇苷类化合物。根据化合物的波谱数据分析鉴定为槲皮素(1)、槲皮苷(2)、异懈皮苷(3)、芦丁(4)、异牡荆素(5)、牡荆素(6)、木犀草素-7-O-α-L-鼠李糖(1→6)-β-D-葡萄糖苷(7)、2-phenethyl β-D-glucoside(8)、icariside D1(9)、2-苯乙基-D-芸香甙(10)。其中化合物1-3、5-6、8-10为首次从本属植物中分离得到。 |

| Abstract: |
| The 80% acetone extracts of the fresh leaves of Alchornea trewioides was successively separated by Sephadex LH-20,MCI gel CHP 20P,ODS,and Toyopearl Butyl-650C column chromatography to yield seven flavonoids and three phenylethanoid glycosides. Their structures were elucidated by spectroscopic analyses as:quercetin(1),quercetin-3-rhamnoside(2),quercetin-3-O-β-D-glucopyranoside(3),rutin(4),apigenin-6-C-β-D-glucopyranoside(5),apigenin-8-C-β-D-glucopyranoside(6),luteolin-7-O-a-L-rhamnopyranosyl(1→6)-β-D-glucopyranoside(7),2-phenylethyl β-D-glucopyranoside(8),icariside D1(9),and 2-phenylethyl D-rutinoside(10). Compounds 1-3,5-6,8-10 were isolated from the Alchornea for the first time |
