Sci. Technol. VL - 58 IS - 6 SE - Natural Products DO - 10.15625/2525-2518/58/6/15127 UR - https://vjs.ac.vn/index.php/jst/article/view/15127 SP - 676-684 AB - <p>From the flowers of <em>Amensiodendron Chinese</em> (Merr.) Hu, six known flavonoids, (-)-catechin (<strong>1</strong>), (-)-<em>epi</em>-catechin (<strong>2</strong>), chrysoeriol (<strong>3</strong>), quercetin-3-O-<em>β</em>-D-glucopyranoside (<strong>4</strong>), astragalin (<strong>5</strong>) and kaempferide-3-O-<em>β</em>-D-glucopyranoside (<strong>6</strong>) were isolated. Their chemical structures were elucidated by analysis of the physicochemical parameters, the NMR and mass spectral data, and comparison with those reported in the literatures.</p> ER -
