摘要
金叶子叶经不同溶剂提取、浓缩及多次层析分离，纯化后从这一植物中得到６个化合物。利用波谱和化学方法阐明其结构，计有１１α－羟基－α－香树素（Ⅰ）、β－谷甾醇（Ⅱ）、槲皮素（Ⅲ）、槲皮素－３－Ｏ－α－阿拉伯呋喃糖甙（Ⅳ）、槲皮素－３－Ｏ－α－鼠李吡喃糖甙（Ⅴ）、槲皮素－３－Ｏ－β－半乳吡喃糖甙（Ⅵ）。总黄酮经小鼠的初步药理试验。
The leaves of Craibiodendron yunnanense W.W. Smith collected from Yunnan Province were extracted by organic solvents with different polarity. After chromatography for many times and purification, six compounds were isolated for the first time from this plant. On the basis of determination of physical and chemical properties and spectral analyses they were identified as 11 α hydroxy α amyrin(Ⅰ), β sitosterol(Ⅱ), quercetin(Ⅲ), quercetin 3 O α arabinofuranoside(Ⅳ), quercetin 3 O α rhamnopyranoside(Ⅴ), quercetin 3 O β galactopyranoside(Ⅵ). The pharmacological verification of crude flavonoids was made preliminarily on mice, the results showed it has central inhibition.
