Studies on the chemical constituents from the aerial parts of Cimicifuga dahurica / 药学学报

<p><b>AIM</b>To seek for new bioactive constituents from the aerial parts of Cimicifuga dahurica.</p><p><b>METHODS</b>Various column chromatographic techniques were employed for the isolation and purification of the ingredients. The structures were elucidated on the basis of 1H, 13CNMR, 1H-1H COSY, HMQC, NOESY and HMBC spectra and chemical reactions.</p><p><b>RESULTS</b>Two cyclolanostanol xylosides, cimidahuside C and D were isolated from the EtOAc section of EtOH extracts.</p><p><b>CONCLUSION</b>Cimidahuside C(1) and D(2) are new triterpenoid xylosides.</p>
