Two new norditerpenoid alkaloids, blacknine [1] and blacknidine [2], have been isolated from the whole plants of Delphinium elatum var. "black night" along with six known alkaloids. The structures of the new alkaloids 1 and 2 were derived from their spectroscopic data (1H, 13C, DEPT, COSY, HETCOR, and selective INEPT nmr experiments). The phytochemistry of this plant variety has not been examined previously.
从高飞燕草变种“黑夜”的全株中分离出了两种新的去甲二萜生物碱，黑九碱[1]和黑啶碱[2]，同时还分离出了六种已知生物碱。新生物碱1和2的结构是通过它们的光谱数据（1H、13C、DEPT、COSY、HETCOR和选择性INEPT核磁共振实验）推导出来的。此前尚未对该植物变种的植物化学进行过研究。
