Seven triterpenoids have been isolated from the roots of Euphorbia nematocypha Hand-Mazz. through chromatography on 20% AgNO3-silica gel. One of them was identified as a new compound named nematocyphol on the basis of spectral data (IR, EIMS, 1H-NMR and 13C-NMR). Its structure was deduced as IVa. Other compounds were identified as nepehinol acetate (I), germanicol acetate (II), euphol (III), tanaxastanol (Va), 24-methylenecycloartanol (VIa) and nepehinol (VIIa). These compounds were obtained for the first time from this plant.
通过在20%硝酸银硅胶上进行柱色谱分离，从线叶大戟的根中分离出了七种三萜类化合物。其中一种根据光谱数据（红外光谱、电子轰击质谱、核磁共振氢谱和核磁共振碳谱）被鉴定为一种名为线叶大戟醇的新化合物。其结构推导为IVa。其他化合物分别被鉴定为乙酸新贝皮醇酯（I）、乙酸吉曼醇酯（II）、大戟醇（III）、蒲公英赛醇（Va）、24-亚甲基环阿尔廷醇（VIa）和新贝皮醇（VIIa）。这些化合物首次从该植物中获得。
