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