A new 9,19-cyclolanostane-type triterpene xyloside (1), from the rhizomes of Cimicifuga racemosa, has been isolated together with four known saponins; cimiaceroside A, 25-O-methylcimigenol-3-O-β-D-xylopyranoside, 27-deoxyactein and 23-O-acetylshengmanol-3-O-β-D-xylopyranoside. The structure of the new compound was established as 16β, 23 : 22β, 25-diepoxy-12-acetoxy-3β, 23,24β-trihydroxy-9,19-cyclolanost-7-ene-3-O-β-D-xylopyranoside. For the structure elucidation, 1D-and 2D-NMR experiments and high resolution electrospray ionzation Fourier transformation mass spectrometry (HRESIFTMS) were used.
