Abstract
A new C27N3-type Lycopodium alkaloid consisting of two decahydroquinolines and a piperidine, cryptadine C (1) was isolated from Lycopodium cryptomerinum. The structure and relative configuration of 1, which is related to those of cryptadines A and B, lycoperine A, and hupercumine A, was elucidated on the basis of spectroscopic data. Cryptadine C showed moderate inhibitory activity against acetylcholinesterase.
