从陕北产甘草Clycyrrhiza uralensis Fisch)的根中分离出五种结晶,分别鉴定为β-谷甾醇(β-sitosterol),芒柄花黄素(Formononetin)甘草西定(Licoricidin)及甘草利酮(Licoricone)。晶V为一新成分,命名为甘草新木脂素(Liconeolignan)其化学结构用化学降解和光谱分析定为[Ⅳa]。
Five crystals were isolated from the roots of licorice Clycyrrhiza uralensis Fisch in northern Shaanxi and identified as β-sitosterol, Formononetin, Licoricidin and Licoction. Licoricone). Crystal V is a new component, named Liconolignan, whose chemical structure was determined by chemical degradation and spectroscopic analysis as [IVa].
