Two new flavans from the roots of <i>Dianella ensifolia</i> (L.) DC

<p>Two new flavans, named (2<i>S</i>)-2′,4′-dihydroxy-7-methoxy-8-methylflavan (<b>1</b>) and (2<i>S</i>)-2′-hydroxy-4′,7-dimethoxy-8-methylflavan (<b>2</b>) were isolated from the roots of <i>Dianella ensifolia</i>. Their structures were elucidated by extensive spectroscopic measurements and comparison with data reported in literatures. Compounds <b>1</b> and <b>2</b> displayed cytotoxic effects against cancer cell lines MDA-MB-231, B16-F10, HCT116 and A549.</p>
