巴戟天寡糖研究

Study on Oligosaccharides from Morinda officinalis

目的:对巴戟天(Morinda officinalis)的糖类成分进行化学研究。方法:用活性炭、纤维素和硅胶等色谱法分离,用波谱法对化合物结构进行鉴定。结果:从巴戟天活性部位中分离出6个寡糖类化合物,分别为蔗糖(Ⅰ)、耐斯糖(Ⅱ)、菊粉六糖(Ⅲ)、β-D-果吡喃糖-(2→1)-β-D-果呋喃糖-(2→1)-β-D-果呋喃糖(Ⅳ)、β-D-果吡喃糖-(2→1)-β-D-果呋喃糖-(2→1)-β-D-果呋喃糖-(2→1)-β-D-果呋喃糖(Ⅴ)、β-D-果吡喃糖-(2→1)-β-D-果呋喃糖-(2→1)-β-D-果呋喃糖-(2→1)-β-D-果呋喃糖-(2→1)-β-D-果呋喃糖(Ⅵ)。结论:化合物Ⅳ～Ⅵ为首次从巴戟天属中分离出的化合物。

Objective： To study the oligosaccharides from Morinda officinalis How.Methods：Compounds were isolated by chromatography,and their structures were identified by spectral analysis and chemical evidences.Results：six compounds were isolated and identified as sucrose（Ⅰ）,inulin-type trisaccharide（Ⅱ）,inulin-type hexasaccharide（Ⅲ）,inulotriose（Ⅳ）,inulotetraose（Ⅴ）,inulopentaose（Ⅵ）.Conclusion： Compound Ⅳ,Ⅴ and Ⅵ are isolated from Morinda officinalis for the first time.
