从lycyrrhiza inflata （Leguminosae）的根中分离到两个新的查尔酮，licochalcone C和D，以及已知的3个查尔cone echinatin， licochalcone A和b。通过波谱分析，它们的结构分别为4,4'-二羟基-2-甲氧基-3-丙烯基查尔酮和2-甲氧基-3'-丙烯基-3,4,4'-三羟基查尔酮。从这种植物中获得的所有查尔酮都是后查尔酮，在2'位置缺乏氧功能。简要讨论了后查尔酮的生物发生与甘草属化学分类的关系。
Two new chalcones, licochalcones C and D, were isolated from the root of lycyrrhiza inflata (Leguminosae) together with three known chalcones echinatin, licochalcones A and B. Their structures were elucidated as 4,4'-dihydroxy-2-methoxy-3-prenylchalcone and 2-methoxy-3'-prenyl-3,4,4'-trihydroxychalcone, respectively, on a spectroscopic basis. All chalcones obtained from this plant are retrochalcones and lack an oxygen-functionality at the 2'-position. The biogenesis of retrochalcones is briefly discussed in relation to the chemotaxonomy of the genus Glycyrrhiza.
