Two new quaternary protoberberines, thalifaurine and dehydrodiscretine, were isolated from the ethanolic extract of Thalictrum fauriei Hayata. Based on spectral analysis and correlation with compounds of known structure, thalifaurine was shown to be 3-hydroxy-2-methoxy-10,11-methylenedioxyberbinium chloride and dehydrodiscretine was established as 3-hydroxy-2,20,11-trimethoxyberbinium chloride. The
从拟南芥中的乙醇提取物中分离出了两种新的四氢小ber碱,一种是沙丁胺碱,一种是脱氢二氢豆腐胺。基于光谱分析和与已知结构的化合物的相关性,沙丁胺碱被证明是3-羟基-2-甲氧基-10,11-亚甲基二氧基铍氯化物,而脱氢二萘烷被确定为3-羟基-2,20,11-三甲氧基氯化铍。通过两种化合物的合成证实了结构分配。还分离并鉴定了Magnoflorine。
