從中藥浮萍的正品紫萍的乙醇提取物中分離出4個黃酮化合物,經(jīng)理化常數(shù)和光譜鑒定其結(jié)構(gòu),分別為芹菜素(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-gluco-side),它們是紫萍中的主要化學(xué)成分。

Four flavonoids were isolated from the ethanolic extract of Spirodela polyrrhixa CL.) 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 constituents of S. polyrrhixa.
