摘要:

利用3种双酯型乌头碱(乌头碱、新乌头碱、次乌头碱)经水解得到3种单酯型乌头碱,即苯甲酰乌头碱(化合物1)、苯甲酰新乌头碱(化合物2)、苯甲酰次乌头碱(化合物3). 应用1D和2D NMR(包括1H-1H COSY、HMQC和HMBC)对这3种化合物的结构进行了分析,纠正了文献对化合物1和化合物2的归属错误,对化合物31H和13C化学位移进行了全归属.

Abstract:

Monoester-diterpenoid aconines (benzoylaconine, benzoylmesaconine, and benzoylhypaconine were obtained by hydrolysis of corresponding diester-diterpenoid aconines (i.e., aconitine, mesaconitine and hypaconitine). 1H,13C and two-dimensional (including 1H-1H COSY, HMQC and HMBC) NMR spectra of the compounds were acquired and assigned. The structures of the compounds were elucidated.

Key words: NMR, chemical shift, 2D NMR, monoester-diterpenoid aconine
