A new lycopodine alkaloid from Huperzia serrata

摘要

A new lycopodine alkaloid, 6α, 11α-dihydroxylycopodine, and three known compounds L20, lycoposerramine K, and huperzine A were isolated from the stems of Huperzia serrata. The structure of the new alkaloid was established by spectroscopic methods, especially two-dimensional NMR techniques.
