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.
