<div><p>A new anthraquinone, morinquinone, together with 18 known anthraquinones were isolated from the stems of <i>Morinda elliptica</i> Ridl. Their structures were elucidated on the basis of spectroscopic data. They each showed weak inhibitory activity against a susceptible strain of <i>Staphylococcus aureus</i> and a methicillin-resistant <i>S. aureus</i>. Damnacanthal was effective against <i>Microsporum gypseum</i> (MIC 1 μg/mL). Lucidin was active against <i>Entamoeba histolytica</i> (MIC 31.25 μg/mL) and <i>Giardia intestinalis</i> (MIC 7.8 μg/mL).</p></div>
