  • Beschreibung: <jats:title>Abstract</jats:title><jats:p>Two glycosides <jats:bold>2</jats:bold> and <jats:bold>3</jats:bold> of the formerly undescribed triterpene 3β,23,27,29‐tetrahydroxyolean‐12‐en‐28‐oic acid (<jats:bold>4</jats:bold>) have been isolated from the aerial parts of <jats:italic>Polygala chamaebuxus</jats:italic> L. In addition, a prosapogenin, obtained by basic hydrolysis of a mixture of bidesmosidic saponins, has been identified as tenuifolin (<jats:bold>1</jats:bold>). The structures have been established by spectroscopic (IR, <jats:sup>1</jats:sup>H‐and <jats:sup>13</jats:sup>‐C‐NMR, DCI‐ and FAB‐MS) and chemical methods (acid, basic, and enzymatic hydrolysis, acetylation, bromination).</jats:p>
