陕西艾叶化学成分的研究

Studies on the Chemical Constituents of Shanxi Artemisia argyi

通过硅胶、Sephadex LH-20反复柱层析、纯化，从陕西艾叶Artemisia argyi的80％乙醇提取中分离到3个化合物，利用NMR、IR和MS等方法鉴定其结构分别为：正十六烷酸（1）、5，7，4’-三羟基黄酮（2）、2，3，3’-三羟基喹啉（3）。其中化合物2和3为首次从该植物中分离得到。

By silica gel and Sephadex LH-20 column chromatography methods,three compounds were isolated from Artemisia argyi. On the basis of spectral data, they were identified as n-hexadecanoic acid （ 1 ）, 5,7,4＇-trihydroxyflavanone （2） ,2,3,3 ＇- trihydroxyquionline （3）. Compounds 2 and 3 were found in this plant for the first time.
