TITLE:
摘要: 目的:研究苗药大乌泡茎乙醇提取物的化学成分。方法:采用硅胶柱、制备液相色谱、Sephadex LH-20凝胶柱等对大乌泡茎乙醇提取物进行分离纯化,根据理化性质和波谱(质谱、氢谱、碳谱)数据分析鉴定化合物结构。结果:从大乌泡茎乙醇提取物中分离得到10个化合物,分别鉴定为5,4′ -二羟基-8-(3,3-二甲基烯丙基)-2″ ,2″ -二甲基吡喃[5,6 ∶ 6,7]异黄酮(1)、3-羟基-1-(4′ -羟基-3′ -甲氧基苯)-1-丙酮(2)、3β-羟基豆甾-5-烯-7-酮(3)、羽扇豆醇(4)、松柏醛(5)、反式对羟基肉桂酸(6)、染料木黄酮(7)、1-O-对羟基肉桂酰单甘油酯(8)、东莨菪内酯(9)、山柰酚(10)。结论:化合物1~9均为首次从大乌泡植物中分离得到,化合物2、5、8为首次从悬钩子属植物中分离得到。该研究可为大乌泡的进一步开发利用奠定基础。
ABSTRACT: OBJECTIVE: To study the chemical constituents in ethanol extract from the stem of Miao medicine Rubus multibracteatus. METHODS: The ethanol extract from the stem of Miao medicine R. multibracteatus was isolated and purified by silica gel column, preparative liquid chromatography and Sephadex LH-20 gel column, etc. The structure of compounds were analyzed and identified according to physicochemical properties and spectrum data (MS, hydrogen spectrum and carbon spectrum). RESULTS: Ten compounds were isolated from the ethanol extract of R. multibracteatus stem, i.e. 5,4′-dihydroxy-8-(3,3-dimethylally)-2″ ,2″ -dimethylpyrano [5,6 ∶ 6,7] isoflavone(1),3-hydroxy-1-(4′-hydroxy-3′-methoxyphenyl)propan-1-one(2),3β-hydroxysitost-5-en-7-one(3),Lupeol(4),Coniferaldehyde(5),E-p-hydroxy-coumaric acid(6),Genistein(7),1-O-p-coumaroylglycerol(8), Scopoletin(9), and Kaempferol(10). CONCLUSIONS: Compound 1-9 are isolated from the plants of R. multibracteatus for the first time, and Compound 2, 5, 8 are isolated from the plants of Rubus L. for the first time. The study lays the foundation for further development and utilization of R. multibracteatus.
