From the roots of Aconitum crassicaule, four diterpenoid alkaloids were isolated. Two of these were identified as chasmanine (5) and yunaconitine (4). The other two, crassicauline A and crassicauline B, are new alkaloids. The structure of crassicauline A, C (35)H (49)O (10)N, has been elucidated as structure (1) on the basis of chemical and spectral data, while the structure of crassicauline B, C (27)H (31)O (4)N, is still to be determined.
从乌头属植物粗茎乌头的根部分离得到了四个二萜生物碱。其中两种鉴定为扎那亭（5）和新乌宁碱（4）。另外两种，粗茎乌头碱 A 和粗茎乌头碱 B，是新的生物碱。根据化学和光谱数据，粗茎乌头碱 A，C（35）H（49）O（10）N 的结构被阐明为结构（1），而粗茎乌头碱 B，C（27）H（31）O（4）N 的结构仍有待确定。
