附子的新二萜生物碱

One new diterpenoid alkaloid from Aconitum carmichaeli

摘要: 采用Al₂O₃、硅胶柱色谱及制备高效液相色谱等方法对附子Aconitum carmichaeli的化学成分进行分离纯化，通过NMR，MS，和单晶X衍射等波谱技术鉴定化合物结构，分离鉴定了4个化合物，分别为:(13R，15S，19S)-13，15，19-三羟基-海替生( 1 )，附子灵( 2 )，尼奥灵( 3 )，和北乌亭( 4 )。其中化合物 1 为新化合物。

Abstract: Four compounds were isolated from the lateral roots of Aconitum carmichaeli by Al₂O₃, silica gel and preparative HPLC. Their structures were identified as: (13R, 15S, 19S)-13, 15, 19-triol-hetisan( 1 ), fuziline( 2 ), neoline( 3 )and beiwutine( 4 ), by methods of NMR, MS spectroscopy as well as single crystal X-ray crystallography. Among them, compound 1 was considered as a new diterpenoid alkaloid.
