Twenty-five diterpenoid alkaloids were isolated from the roots of two Aconitum species. The structures of seven new C19-diterpenoid alkaloids, apetaldines A–G (17), and 10 known alkaloids (817) from Aconitum apetalum and eight known alkaloids (1825) from Aconitum franchetii var. villosulum were elucidated via HRESIMS, IR, and NMR data. Alkaloids 110, 15, 16, and 1825 were screened for their antifeedant activity. Among the compounds tested, chasmanthinine (19) showed highly potent antifeedant activity with an effective concentration for 50% feeding reduction (EC50) at 0.07 mg/cm2. The antifeedant structure–activity relationship of the diterpenoid alkaloids is also discussed.

两种乌头类双萜生物碱具有对夜蛾的拒食活性。

从两个乌头物种的根中分离出二十五个二萜类生物碱。七个新的C结构19种-diterpenoid生物碱,apetaldines A-G(17),和10种已知生物碱(8 - 17)从乌头apetalum和8种已知生物碱(18 - 25)从乌头franchetii变种。villosulum分别经由HRESIMS,IR,和NMR数据阐明。生物碱1 - 101516,和18 - 25筛选其拒食活性。在所测试的化合物中,黄花氨酸(19)在0.07 mg / cm 2的有效浓度下可有效降低50%的进食量(EC 50)。还讨论了二萜类生物碱的拒食结构与活性的关系。
