【摘要】 对天然橡胶胶清的化学成分进行了研究。运用硅胶柱色谱及葡聚糖凝胶LH-20柱色谱进行化学成分的分离和纯化,用理化方法及波谱手段解析其化学结构。从天然橡胶胶清中分离得到13个化合物,鉴定了其中12个化合物的结构,分别为:木栓酮(Ⅰ)、羽扇豆醇(Ⅱ)、β-谷甾醇(Ⅲ)、棕榈酸(Ⅳ)、硬脂酸(Ⅴ)、胡萝卜苷(Ⅵ)、尼古丁酸(Ⅶ)、琥珀酸(Ⅷ)、没食子酸(Ⅸ)、果糖(Ⅹ)、白坚木皮醇(Ⅺ)和6-hydroxy-cleistopholine(Ⅻ)。经检索,其中化合物Ⅰ、Ⅱ、Ⅵ、Ⅶ、Ⅸ和Ⅻ为首次从天然橡胶胶清中分得。更多还原

【Abstract】 The chemical constituents of the Hevea brasiliensis skim were studied.Compounds were isolated and purified by silica gel column chromatography and Sephadex LH-20.Their structures were identified by physicochemical properties and spectral analyses.Thirteen compounds were obtained and the twelve ones of them were identified : Friedelin(Ⅰ),Lupeol(Ⅱ),β-Sitosterol(Ⅲ),Hexadecanoic acid(Ⅳ),Heptadecanoic acid(Ⅴ),Daucosterol(Ⅵ),Nicotine acid(Ⅶ),Succinic acid(Ⅷ),Gallac acid(Ⅸ),Fructose(Ⅹ),Quebrachitol(Ⅺ),6-hydroxy-cleistopholine(Ⅻ).Compounds Ⅰ,Ⅱ,Ⅵ,Ⅶ Ⅸ and Ⅻ were isolated from Hevea brasiliensis skim for the first time.更多还原
