The alkaloids of Lycopodium clavatum var. megastachyon have been examined and two hitherto unreported alkaloids, lycoclavine and acetyllycoclavine, were isolated and their structures determined. The nuclear magnetic resonance spectra of these and related compounds are discussed in terms of the conformation of ring B in these alkaloids.
