A new flavanolignan and a new alkane from the Stem bark of <i>Newtonia griffoniana</i>

<p>Two new compounds a flavanolignan (<b>1</b>), and an alkane (<b>2</b>) along with four known compounds including two fatty acid esters (<b>3–4</b>) and two isocoumarins (<b>5–6</b>) were isolated from the methanolic extract of the stem bark of <i>Newtonia griffoniana</i>. Their structures were elucidated using spectroscopic methods including extensive 1-D and 2-D NMR experiments.</p>
