Abstract
A new lycodine alkaloid, N-methylhydroxypropyllycodine (1), was isolated from the club moss Lycopodium japonicum Thunb, together with five known compounds, N-methyllycodine (2), huperzinine (3), β-obscurine (4), α-obscurine (5) and des-N-methyl-α-obscurine (6). Their structures were elucidated by spectroscopic analyses, including 2D NMR techniques.
Keywords:
