Lycopodiumalkaloids fromHuperzia serrata

Journal of Asian Natural Products Research, 2010
A new lycopodane-type Lycopodium alkaloid, 6α-hydroxy-5,15-oxide-lycopodane (1), and seven known alkaloids were isolated from the whole plants of Huperzia serrata. Their structures were elucidated by means of spectroscopic methods. 12-Deoxyhuperzine O (2) was reported as a naturally occurring alkaloid for the first time, and showed an antagonist effect

Huperserines A–E, Lycopodium alkaloids from Huperzia serrata

Fitoterapia, 2014
A phytochemical study on Huperzia serrata led to the isolation of four new 5-deoxyfawcettimine-related Lycopodium alkaloids, huperserines A-D (1-4), and one new lycodine-type alkaloid, huperserine E (5). Their structures were elucidated based on spectroscopic data, including 1D and 2D NMR techniques.
