目的 研究毛木防己Cocculus orbiculatus var.mollis根中的生物碱类化学成分.方法 利用硅胶柱色谱及重结晶方法分离纯化,通过化学及波谱分析方法鉴定化合物的结构.结果 从毛木防己根95%乙醇提取物中分离并鉴定了1个较少见的C-α羟基取代的新BBI生物碱木防己亭碱(1)及3个已知生物碱,分别为去氢艾帕特啉碱(2)、木防己碱(3)、异木防己碱(4).结论 化合物1为新化合物,命名为木防己亭碱,化合物2~4为首次从该植物中分离得到.
Objective To study the alkaloid compounds in the roots of Cocculus orbiculatus var.mollis.Methods The compounds were isolated by silica gel chromatography,and their structures were established by spectroscopic methods.Results A novel cocsolines-type bisbenzylisoquinoline alkaloid named orbiculatinine (1),along with three known compounds (+) 1,2-dehydroapateline (2),trilobine (3),and isotrilobine (4),were isolated.Conclusion Compound 1 is a new compound named orbiculatinine.Compounds 2-4 are isolated from this plant for the first time.
