| 摘要: |
| 分离鉴定爵床科观音草属植物山蓝的化学成分。采用硅胶柱色谱、重结晶方法对山蓝乙醇提取物进行分离纯化,利用红外、质谱、核磁共振技术进行结构鉴定,得到15个化合物,分别为二十八醇(1),硬脂酸(2),β-谷甾醇(3),豆甾醇(4),棕榈酸(5),月桂酸(6),尿囊素(7),棕榈醇(8),芝麻素(9),齐墩果酸(10),β-胡萝卜苷(11),尿嘧啶(12),腺嘌呤(13),十八烷基葡萄糖苷(14),柠檬酸(15)。除β-谷甾醇,豆甾醇和β-胡萝卜苷外,其余12个化合物均为首次从该植物中分离得到。 |

| Abstract: |
| Chemical investigation on ethanol extract of Peristrophe roxburghiana yielded 15 compounds by column chromatography and recrystallization. Their structures were elucidated by IR,MS and NMR techniques as Octacosanol(1),Stearic acid(2),β-Sitosterol(3),Stigmasterol(4),Palmic acid(5),Lauric acid(6),Allantoin(7),Hexadecanol(8),Sesamin(9),Oleanolic acid(10),β-Daucosterol(11),Uracil(12),Adenine(13),Octadecyl-glucoside(14)and Citric acid(15),respectively. And all the compounds except 3,4 and 11 were obtained and reported from P. roxburghiana for the first time. |
