摘要
从腺梗豨签Siegesbeckiapubescens的乙醇浸膏中又分得2个新化合物,利用二维核磁共振技术,结合质谱和红外光谱确定的结构,分别为12-羟基奇任醇和2-酮基-16-乙酰基奇任醇。
Plants of the genus Siegesbeckia L. have been used as a Chinese traditional medicine, 'Xi Xian', for expelling wind,removing dampness,and relieving rigidity of muscles and joints. In this thesis,the chemical constituents of the herb S. pubescens were studied. Two novel compounds were isolated from its ethanol extract,the structures of which were identified by spectral methods of 2D NMR,MS and IR,as 12-hydroxy-kirenoland 2-keto-16-acetyloxykirenol.
