浮萍的化学成分研究

Studies on the Chemical Constituents of Common Ducksmeat (Spirodela polyrrhiza)

从中药浮萍的正品紫萍的乙醇提取物中分离出４个黄酮化合物，经理化常数和光谱鉴定其结构，分别为芹菜素（ａｐｉｇｅｎｉｎ）、木犀草素（ｌｕｔｅｏｌｉｎ）、芹菜素－７－Ｏ－葡萄糖苷（ａｐｅｇｅｎｉｎ－７－Ｏ－ｇｌｕｃｏ－ｓｉｄｅ）和水犀草素－７－Ｏ－葡萄苷（ｌｅｕｔｅｏｌｉｎ－７－Ｏ－ｇｌｕｃｏｓｉｄｅ），它们是紫萍中的主要化学成分。

Four flavonoids were isolated from the ethanolic extract of Spirodela polyrrhiza (L. ) Schleid.. Their structures were identified by spectral analysis and chemical evidences, as apigenin, luteolin, apigenin-7-O-glucoside, and luteolin-7-O-glucoside. All of them were the main coustituents of S. polyrrhiza.
