Isolation of a new lycodine alkaloid from <i>Lycopodium japonicum</i>

Abstract

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