| 中文摘要:对构树叶的化学成分进行分离和鉴定。方法：用D101型大孔吸附树脂、正相硅胶、反相硅胶等柱色谱进行分离、纯化，利用NMR和ESI-MS技术确定结构。结果：分离鉴定了7个化合物,分别为正十八碳酸甲酯(1)，正十九碳酸(2)，邻苯二甲酸二甲酯(3)，木犀草素-6-C-β-D-葡萄糖碳苷(4)和木犀草素-8-C-β-D-葡萄糖碳苷(5),大波斯菊苷(6)和木犀草素-7-O-β-D-葡萄糖苷(7)。结论：化合物1、2、3为首次从构树叶中分离得到。 |

| Abstract:To isolate and identify the constituents from the leaves of Broussonetia papyrifera (L.) Vent.. Methods: Compounds isolation used D101 macroporous resin, silica gel and ODS column chromatography methods.Structures identification used NMR and ESI-MS techniques. Results: Seven constituents， including n-hexadecanoic acid methyl ester, n-nonadecanoic acid, dimethyl phthalate, luteolin-6-C-β-D-glycosides, luteolin-8-C-β-D-glycosides, cosmosiin and luteolin-7-O-β-D-glucopyranoside were identified. Conclusion: It’the first time of n-hexadecanoic acid methyl ester, n-nonadecanoic acid and dimethyl phthalate isolated from leaves of B. papyrifera. |
