Objective To study the alkaloids from Tengshisong [Lycopodiastrum casuarinoides (Spring) Holub]. Methods The total alkaloid fraction of L. casuarinoides was separated and purified by various chromatographic techniques. The chemical structures were identified by comprehensive spectroscopy analysis and single crystal X-ray diffraction. Results A total of eleven compounds were isolated from the total alkaloid fraction of L. casuarinoideds, and the structures were identified as 6-hydroxy-β-obscurine (1), des-N-methyl-β-obscurine (2), casuarine B (3), huperzine B (4), casuarinine B (5), β-obscurine (6), huperzinine (7), N-demethylhuperzinine (8), huperzine C (9), 8,15-dihydrohuperzinine (10), and casuarinine I (11). Conclusion Compound 1 is a new Lycopodium alkaloid.
