摘要
目的：研究花萼苔的化学成分。方法利用硅胶柱、SePhadex LH-20、高效液相色谱等色谱技术进行分离纯化，通过理化性质和波谱数据确证其结构。结果从花萼苔中共分离得到5个化合物，分别鉴定为三裂鼠尾草素（1）、5-羟基-6，7，4＇-三甲氧基二氢黄酮（2）、3-醛基吲哚（3）、对-羟基苯甲醛（4）以及-谷甾醇（5）。结论化合物1～5均为首次从该属植物中分离得到。
Objective To investigate the chemical constituents of Asterella angusta. Methods The chemical constitu-ents were isolated by silica gel,Sephadex LH-20,and HpLC chromatographies. Their structures were elucidated based on spectral evidence together with physiochemical properties. Results Five compounds were isolated and identified as salvige-nin（1）,5 -hydroxy-6,7,4＇-trimethoxyflavonone（2）,indole-3 -carboxaldehyde（3）,p-hydroxybenzaldehyde（4）,-sitosterol（5）,respectively. Conclusion Compounds 1～5 were isolated from this plant in aytoniaceae for the first time.
