黄花菜根化学成分研究

Study on Chemical Constituents from the Root of Hemerocallis citrina

目的:对陇东地区产的黄花菜根的化学成分进行研究。方法:采用微波80%乙醇浸提法和硅胶柱色谱分离纯化,根据理化性质和波谱数据鉴定结构。结果:从黄花菜的80%乙醇提取物中共分离鉴定出7个化合物,分别为:大黄酚(Ⅰ)、美决明子素甲醚(Ⅱ)、美决明子素(Ⅲ)、大黄酸(Ⅳ)、芦荟大黄素(Ⅴ)、萱草酮(Ⅵ)、萱草素(Ⅶ)。结论:其中,化合物Ⅳ、Ⅵ为首次从该植物中分离得到。

Objective： To study the chemical constituents root of Hemerocallis citrina.Methods： The chemical constituents were extracted by microwave method and purified by silica gel column.Their structures were elucidated by their physical and chemical properties and spectral methods. Results： 7 compounds were isolated and identified as： chrysophanol（Ⅰ）,2-methoxy-obtusifolin（Ⅱ）,obtusifolin（Ⅲ）,rhein（Ⅳ）,aloe-emodin（Ⅴ）,hemerocallone（Ⅵ） and hemerocallin（Ⅶ）.Conclusion： Compounds ⅣandⅥ are isolated from this plant for the first time.
