New alkylamide from the stems of <i>Zanthoxylum nitidum</i>
<p>A new alkylamide, named (2<i>E</i>,6<i>E</i>,8<i>E</i>)-<i>N</i>-(2-methylpropyl)-10-oxo-2,6,8-decatrienamide (<b>1</b>), together with 22 known compounds (<b>2–</b><b>23</b>), were isolated from the stems of <i>Zanthoxylum nitidum</i>. Their structures were elucidated by spectroscopic methods, including 1D and 2D NMR spectroscopy. The isolated compounds exhibited slightly antioxidant activities through DPPH and ABTS radical scavenging assays but showed no antibacterial activity against <i>Streptococcus mutans</i> ATCC2517, a dental caries causing bacteria.</p
