title: Two new norditerpenoid alkaloids from Delphinium elatum var. "black night".
abstract: 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.
