百尾参根的化学成分研究

Chemical Constituents of Disporum cantoniense

目的： 研究百尾参Disporum cantoniense（Lour.）Merr.乙酸乙酯部位的化学成分。 方法： 利用硅胶色谱及重结晶进行化学成分分离与纯化，根据化合物的理化性质和光谱数据鉴定其根结构。 结果： 从百尾参根中分离鉴定了6个化合物，分别为：大黄素甲醚（physcion， 1）、大黄素（emodin， 2）、豆甾醇（stigmasterol， 3）、槲皮素（quercetin， 4）、β-谷甾醇（β-sitosterol， 5）、β-胡萝卜苷（daucosterol， 6）。 结论： 化合物 1~4 为首次从该植物中分离得到。

Objective： To study the constituents of the roots of Disporum cantoniense in extracting with ethyl acetate. Method： The compounds were separated and purified by silica gel and recrystallisation. Their structures were identified by their physico-chemical properties and spectroscopic data. Result： Six compounds were isolated and identified as physcion（1）,emodin（2）,stigmasterol（3）,quercetin（4）,β-sitosterol（5）,daucosterol（6）. Conclusion： Compounds of 1-4 were obtained from this plant for the first time.
