title: Two new N-oxide Lycopodium alkaloids from Huperzia serrata.
abstract: Two new Lycopodium alkaloids, N-oxidehuperzine E (1) and N-oxidehuperzine F (2), along with two known alkaloids, huperzines E (3) and F (4), were isolated from Huperzia serrata (Thunb.) Trev. Their structures were elucidated by spectroscopic and chemical transformations.
