Three new triterpenoid saponins from <i>Albizia julibrissin</i>

<p>Three new triterpenoid saponins, julibrosides A₅–A₇ (<b>1–3</b>), together with five known saponins (<b>4–8</b>), were isolated from the stem bark of <i>Albizia julibrissin</i>. Their structures were elucidated on the basis of extensive spectroscopic data analysis of MS, 1D and 2D NMR, and chemical methods. Compounds <b>7</b> and <b>8</b> were isolated from the genus <i>Albizia</i> for the first time. The new compounds showed no cytotoxicity and anti-inflammatory activity.
